Drawing in the Sand

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.

How to sand without sand paper?

 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!

Green sand options? Answered

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?

Sweet Sand Sculptures

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.

Separate Sand and Water in Glass Vase

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.

Using an inkjet to print water based glue?

I am thinking about playing with an inkjet printer to print 3d sand casting molds. To save time, I won't be too specific in my design, but I basically want to modify an inkjet to print a water based glue onto layers of sand to create sand casting molds like the 3d printer in this video: http://www.youtube.com/watch?v=Z8MaVaqNr3U Someone also made a crude version of what I want in this video: http://www.youtube.com/watch?v=2nbtZOolSIY&feature;=player_embedded My theory is that if an inkjet printer heats up the water in the ink creating a bubble of steam to push the rest of the ink out, wouldn't the same concept apply to a water based glue if you put that in the inkjet? So here are my questions: 1) Would it be possible to put water based glue in an inkjet and have it print it? 2) Are water based glues are ok to use in sand casting molds? Tell me what you think and thanks for your input.

Just found out: Clean inside of a thermos - Simple!

I just had to clean my thermos prior the tournament tomorrow. A quick peek inside revealed some stubborn residue. Propably furring (chalky deposits) from the boiling water i use to make tea in them... (we have quite "hard" water with lots of calcium). The throat of the bottle (Full-metal thermos) was too narrow for normal cleaning-brushes... I fortunately had a bag of rice standing around and thought  "Hm... Hard and small things"! So i quickly added half a handfull of dry rice in the thermos and a bit of cold water (2-3 spoons). Then i shook it a bit and poured the rice out. The inside was quite clean and almost "pristine" again. This method should also work for thermoscans with glass-interiors. Another (better) way of doing that is propably (but ONLY if you have a METAL-Interior!) to add a hand of sand or fine gravel with some wather (Maybe even a bit of dishsoap) and give it a shake. Again: Only do the sand/gravel if your thermos does not have a glass-interior!! Have fun and enjoy a good drink while outside! :)

Laser diode cooling, would sanding help?

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.

Sanding small flat surfaces so they stay flat

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

What is a smooth, or "rounded" aggregate, like sand, but NOT abrasive ?

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!
