Artist Jim Denevan makes sand drawings--but on a much bigger scale than your average beachcomber. This one is three miles across, a project that required a mind-boggling 100 miles of walking to complete. After one week, though, a rainstorm made the drawing disappear completely.Link via GeekdadIf you like this, another artist who works in nature is Andy Goldsworthy. Some of his pieces do not last more than a few hours, such as this ice sculpture from :30 to :55 that melted as soon as the sun rose.

I’m new here and just wanted to share what I do. I have been glass sandcarving for over 20 years and used to teach it.

 So my question is, is there a fairly efficient way to sand  something without using sandpaper? I am doing a project for haiti, and i just realized a breakdown in a system. Sandpaper would add a huge cost to anything.  Right to what it is used for: I was wondering, if anyone have any simple ideas on how to sand soda cans after cutting them into sheets? Solutions i can think of in context with whats available in Haiti is may be rubbing the sheets against concrete or even in a sand box?  I am just thinking, back in the old days, before sand paper, how did people do it? any ideas would be really appreciated!

How is it possible that some beaches have hot sand and others have cool sand even in tropics?

I finally finnished my testing prototype of my metal melting furnace. Did a few casts to get short rods for the lathe work and noticed a big problem. I used washed play sand as itwas the finest sand I could find locally. The result was good in shape but very bad in terms of surface quality. For another test I used the leftovers of my crushed perlite and mixed it bentonite and the surface was really smooth - but using perlite is not really an option. Real green sand is hard to get in my area and the postage costs for a 20kg bag are just too high on top of it. So, before I start hunting down all sand and soils shops nearby: Is there a proper name for extreme fine sand or a good alternative for a reusable casting media?

I am trying to find instructions for making sand and water pictures where a mixture of sand water and air are trapped between two pieces of glass. By turning the picture upside down the sand, restricted by the air bubbles will produce a unique "landscape" on each occasion. Any help would be much appreciated.

Sand sculptures always amaze me. The good ones, I mean. Mine never progressed much beyond noble walls that were crushed by high tide, but it's great to see that other people kept up with it and can get such amazing results from such a finicky material."Fairy tales and legends" is the theme of this year's World Sand Sculpture Festival now underway at the Tottori Sand Dunes in Tottori prefecture. On display (until May 31) are 19 massive works crafted by world-class sculptors from ten nations. The artists used around 2,700 tons of sand and took about two weeks to complete their works.

Now let's try our hands at critical thinking and experimental design. I have a very simple question for you; what is the average volume of one grain of sand ? 

I just found these on a news website and thought that I would share it! These are some sand sculptures that were made in Australia a few weeks ago...They are absolutely dazzling! They are the biggest and best sand sculptures I have ever seen! Hope you like them!

Anybody have a tip on how to sand smooth many small discs of wood? Rather than do it all by hand with sanding paper I mean… Is there a (cheap) sanding tool that I can purchase? Not something like the Dremel, Im thinking more about something with a flat sanding surface. Thanks anybody that will answer.

Hey guys,I was wondering something.  When you unlock classic prince of persia in sands of time (gamecube) which version is it mac,pc,other? I just wanna know...

I found this video and wanted to know your reactions.http://www.youtube.com/watch?v=IuyQSZX8HMI&NR;=1any1 knoow if it is real?

They market the stuff for installing around playground equipment. It's shredded tires. I got a load free. I plan to use some for backfill in a spot which was very rough to dig out. But I'll have leftovers. Can I vulcanize it into solid rubber? How?  Mix with concrete to make it lightweight? Or will thermal changes cause rubber to expand /contract too much?   What else could be done w/ it?  

How do you make one of thos thing that you flip over and see the sand fall down? my nany wons to make one and can you tell me the name is???????????????????

Does anyone know how to make sand stick together like the archeological sand toys from museums?  I'd like to bury items for a camp and let them dig in their individual sand cakes with popsicle sticks.?

I'd like to hear some suggestions for separating sand and water in a 4" diameter glass vase. I'm doing an arduino project that involves having a dyed deep blue mineral oil as a non-evaporating "water" atop about 4 inches of sand in a glass vase. I experimented with drizzling Loctite epoxy and it leaked about 1/4" into the sand, so it wasn't very elegant (created a layered look - dry sand, wet sand, epoxy, water). I'd like the delineation to be as clean, but easily implemented, as possible. Worst case scenario is that I wrap something around the vase to hide the transition, but I'd like to avoid that if possible.  I suppose another option is to stack 2 separate glass vessels, but im struggling with thinking of a good way to do that too... Perhaps this is also a non-issue...I should see if the deep blue mineral oil is even visible if put directly INTO the sand. Thanks in advance.

Okay so I have been charged with finding out how to build a simple sand/ gravel water filter for use at scouts on Thursday and I have come up with ZERO... Does anyone know enough about it to explain to me in laymans terms on how to construct one... or rather what grades of sand/gravel i need? I'm planning on using a pop bottle, and layering the sand and gravel inside it.... using the screw top end as the tap.... I have a BASIC idea of what i need... I just want to be sure it works! Thanks guys and girls Jay

What will i use to melt it? what will i use as a crucible? what will it turn out as? is it even possible?

Im working on a model truck, and its going to be on  the beach. i just need a paint colour in tamiya, model masters, or testors.ive tried tamiya dark yellow, but i dont rly like it.

I'm looking to tumble porcelain bisque (not the final firing, still soft enough to sand off impefections), and polish the final fired porcelain beads in a tumbler. See attached photos of a final fired porcelain bead for the scale. I'm wondering if you know what media, burnishing compound etc I should be using, and for how long.. I already have a 3lb capacity Lortone Tumbler with stainless steel shot currently for polishing metal. But I believe this tumbler also does rocks.

im making a mini vacation sandbox like this https://www.instructables.com/id/Mini-Vacation-Sandbox/ with my daughter.... we dont have any sand on hand but we do have brown flour.it is midnight right now... i want the "sand" to be stationary as in never move from the place i put it. with shells on top. in past experiance pouring elmers into sand in great quantities the glue did not dry. the "sand" would be about 1/4 in deep. how do i go about turning this wheat flour into something more permanent?

I want to know...for constructing a house flooring...in one bag of cement what is the ratio and proportion of sand and gravels? and how many feet will it cover for that mixture for the floor?

I want to know how many grains of sand are in a cubic mm, because I want to work out how many grains of sand fit in my bedroom (using maths rather then filling it with sand and then counting for the rest of my life.)

I would like to make free standing sculptures and hanging pieces. I would like advice from anyone who has tried this medium. Thanks.

Is there a special type of sandpaper i should use when sanding paint of metal?

If I sanded the sides of my laser diode (essentially the same package as a stubby 5mm led), would it increase the surface area enough so that the cooling effects are noticeable if used in conjunction with thermal epoxy and a small active cooling system? Datasheet: http://docs-europe.electrocomponents.com/webdocs/08d5/0900766b808d55b2.pdfUPDATE: Ok, due to many unforeseen minor issues/problems that have arisen, I have decided to consider a flat diode package. Although the power and pulse width are somewhat smaller, It wont really hinder the end product (which will have loads of documentation on the build here).New diode datasheet: http://catalog.osram-os.com/catalogue/catalogue.do;jsessionid=A8BC7E9CCE6FB1AA392B37F3F982A978?act=downloadFile&favOid;=0200000200001347000300b6

I know pool filter sand is not a major investment. However, I hate throwing the sand away & replacing it if I don't need to. Is it possible to simply remove the sand, clean it, dry it, return it to the filter AND have it work properly?

What would be the best way to attach ~ detach a set of wheels to a boat ... to move across soft sand ?  .. weight capacity = 500 lbs How to build balloon sand tires thanx ~Frog~

Is there a better way to mold aluminium into tableware than using green sand molds?

When I saw the sandblaster here, I wanted to make one because well, it's cool. The only problem is that I can't find the gun. From what I can tell, It has 2 intakes and one exit nozzle. I did read the instructable, but it didn't say (as far as I could tell). Can someone help?

I was going to make another sandboard to try a different design, and I was wondering if there was any demand for an Instructable about it. Anyone?

I'm trying to set up a sandblaster, got the compressor, got the gun, it's one of those 30lb over the shoulder plastic containers, but the grit on ebay is so expencive.So can I use ordinary sharp sand? I need it to remove paint and rust.

I'm planning to switch from wood to cement because we are soon moving into a condominium where noise should be kept to a minimum. If yes, what is the ratio of water to cement? if no, can i mix it with sand only and what is the ratio. Thanks

Hi, I'm trying to sand fairly small wooden objects that are about 1/2"x1" and sometimes a little larger. I often find that one side is thicker than the other or the corners are no longer perpendicular. I am trying various techniques, like taking a chunk of 2x4 and wrapping it sandpaper and then vice it to my workbench. Then I rub the object against the paper block. That is getting better results.  I've read that some people use spray-on adhesive to secure sheets of sandpaper to a granite top and that it is supposed to work well. There are a few instructables that explicitly talk about sanding and I've read many of them. They advocate a bunch of techniques. I'm wondering what other folks have had success with. Thanks, Andy

I made an hourglass as a prop for a local production of "The Wizard of Oz".  The "witch" (the actress') still has it at her  home.  The "glass", which s actually plastic, & made of sections cut from 4 plastic goblets- is becoming less clear because the white sand I used is fogging up the surface with very fine scratches.  I'd like to replace this sand (that I got from a craft store, like Joann's) with an aggregate that has smooth round pieces, not rough ones.  These wont be so scratchy, and will also be less apt to cram together and clog the narrow passage from the top chamber to the lower one.  I googled these words, and got some very technical info about the science of manufacturing concrete and plastic products, but nothing I could use to find or even name what I could buy and use.  ALSO, is there a best compound for polishing the inside of the "glass" to restore the original clarity?  In other things, I've used brass polish, and even toothpaste!

I am attempting to connect several pieces of plastic and want to do it nice and smooth, so that when finished it looks like it is suppose to be like that. To that I end I would need to be able to mold, have it air dry, then be able to sand it smooth and paint it. I was thinking of using air dry modeling clay but I do not know how well that would integrate with plastic as well as being able to sand it. Any ideas?

Our home is on sand, lime, sink holes. It helps to direct rainwater away from the structure to prevent sink holes. My question is if there are recommended soil treatments for sand. If it will help to coat the perimeter with two feet of soil and sod, I'll do it. I really like landscaping and I just wanna make sure using a few feet of fertile soil and sod is an option without making things worse. Any other recommendations would be very much appreciated. Thanks all.

Specifically a cheap spanish guitar. Just curious. I know that if I paint too much, it'll kill the tone. And I know I should use a nitrocellulose lacquer (but Ill probs just use Polyurethane). Has anyone had history with this?

I would like to keep my home-made guitar amp a light color. and i am having problems finding the right polyeurathane for it.  it is a very whitish wood, and it does not have any knots, and i like the white color of it. and when i put just plain poly on a scrap of wood, it turned a disgusting yellow. i dont really want that! haha so i wonder if there is a way to keep that beautiful white color on the amp, but still have poly on it. because if i dont poly the amp, it is going to get destroyed by water, dust, and it will, of course, get beat up by random things (little sisters....haha jk). sooo, i just wondered. THX!!

I'm looking to dredge a slip myself. The slip is in Tampa Bay. It has plenty of water during normal tides but not at a strong low tide. Looking to keep my 17ft. safely moored.

Hello there :) This is my first forum post so please be gentle ;) Okay, here's the skinny. I am doing a zakk wylde paint job on my stagg strat. I've removed all the paint and sanded it down. But I have some scratches on it (from the sanding) and a few places where I went in too deep with the sandpaper and removed some of the old sanding sealer. So, I need some sanding sealer / grain filler in order to make it a nice smooth surface so I can apply primer to it. Here's the problem. I live in a country where there is ABSOLUTELY NO DEMAND for sanding sealer / grain filler. So there is nothing like that in Bulgaria. And I need to know how I can make my own. (all of the carpenters here sand it and put on some lacquer and it's an awful finish but that's how it is here) Sooo, can any1 please help mee.... :) I really need something that is a good substitute of grain filler / sanding sealer.

I own an iPod Shuffle, 2nd generation, silver. It is very plain, and I've recently been reading up on saltwater etching. I want to remove the standard Apple logo from the back and etch my own text (it will either be "iMake" or "iBles", I can't decide). I've come upon two roadblocks, so far, those being: can I sand laser etchings (the Apple Logo) off, and can I etch through the player's anodization, or would I need to sand that off? I don't really care if it doesn't turn out perfect, or looks like a total mess. It's not like I paid for the thing. Thanks for any help!

I'm a COMPLETE novice when it comes to resin of any kind. But I'd like to start doing my own flower castings as a hobbie. I was thinking of buying water clear casting resin- I want to be able to see the detail in the pieces but recently after watching a few videos and researching, i've found that I have to go through a sanding process. I thought that if I buy water clear then I wouldn't have to sand it because you will see the details? am I wrong in thinking this. Also,  if I cast items in glass jars will they come out super clear?

Hi All, Trying to make replacement bases for my floor-standing speakers.  The originals were made out of particle board and appear to have a black spray-paint finish.  They were destroyed in the post when the person sending me the speakers failed to package them properly.  I now have the particle board cut to the right shape and I have begun the process of sanding.  It is my intention to spray a primer on, sand, spray a top coat, and then spray some sort of finish.  so here are my questions: (1) I have sanded the board down with successively finer sandpaper and finished with 1500 grit wet and dry.  This is a very smooth finish until you wipe away the dust at which point it becomes rough-ish again.  Having done a bit of research I am now concerned that I have sanded the board down a bit to much, some forums suggest taking the board down only as far as 250 grit before spraying on the primer.  What should be my finishing grit before spraying on the primer?  My assumption was the finer the better but I'm not too sure now.  If the finish should be fine then how do I remove those stubborn fibers? (2) what type of spray primer works best with particle board?  There seems to be a multitude but most of the information related to car/auto body work.   (3) what grit of paper should I use on the primer? (4) what should I use as a top coat? Much thanks in advance Ross
