Sturdy or hard straws for straw rockets?

What is a good source for sturdy straws of plastic tubing that can be used as  an Ultimate Straw Rocket.   It would be good if the straws did not melt with hot glue as cheap thinner straws do.

Instead of tossing them out you can clean them up and make this technicolor lamp that a kid would love.The directions are pretty helpful, but could use some process shots.

Staining a paper straw hat

Hi all. I was recently returned a hat I bought for my ex, it was one of those "I'd like that" moments where I spent a few pounds on something that she changed her mind about before it arrived and has never been worn since, it's not a particularly expensive hat but it is a unisex style essentially just a white straw cowboy style hat in fact I have a similar one in brown. Not being a great lover of white hats I would like to stain it a different colour but as I have never stained paper straw I have no real idea of how best to begin. Suggestions from anyone with experience of this material would be very welcome. Thanks in advance. NG.

Spool of uncut drinking straw tubing, anyone know of a source?

Im designing a system that would fill tubing with a syrup and then sealing the tube off into segments. Honey straws are an example. What Ive seen is people individually filling drinking straws and sealing each end. I think filling a long coiled tube and sealing it into segments is more efficient. Sort of sausage style if that makes sense. I know how everything will work except where to get a very long piece of drinking straw. Or if anyone has a recommendation for a tube I can use in place of this I would take the advice. Im not dead set on drinking straw, its just what everyone seems to use. Ive seen vinyl tubes online but those would impart a chemical flavor so I want to stay away from them.

Baking Polymer Clay on Plastic Straws?

Is it safe to bake polymer clay on plastic straws? I'd like to try making a ball-jointed doll, and one tutorial uses plastic straws as a form of armature for which the polymer is wrapped around to create a hollow core to sculpt on. The straws seemed in-tact, but is it safe? I know certain plastics let off toxic fumes when exposed to certain temperatures, which is why I ask. I would think it would be fine, since it wouldn't be much "foreign plastic" (AKA not the clay) but I'd rather ask and be sure, than find out the hard way. Thanks for any help!

Lamarkian inheritance -- not just a straw-man "mistake"?

A new article in Nature reports on research indicating that developmental changes caused by environment can be passed on to offspring. The Universe is always more complex, and more subtle, then the textbooks and dogmatists would have you believe.Lamarkian inheritance is a theory of genetics where animals could pass on traits which they acquired during life. In the typical textbook oversimplification, the examples used are often the giraffe stretching to reach leaves would have children with longer necks; the blacksmith who developed a highly muscled right arm would have childred with bigger right arms; and so on. After the discovery and rediscovery of Mendelian genetics, Lamarkism was more or less ignored (except by Lysenko), leaving only this simplistic and stupid story of a "mistaken idea" in textbooks.There have been a number of discoveries in recent years of heritable traits (in humans as well as in other animals), for which no specific gene, or even combination of genes, could be isolated. The term "epigenetics" refers to the fact that many of our physical traits are driven, not by genes directly, but rather by the complex biochemistry of how, when, and how much genes are expressed. There have been some examples of epigenetic inheritance, but in all those cases, the pattern of gene expression is itself driven by the presence or absence of nearby "triggering" DNA in the genome.This new article is an example where an epigenetic feature driven by enviornmental influence appears to cause changes that can be passed on to offspring. What the mechanism is (i.e., how the pattern of expression gets "stored" in the germ cells) is not clear, but it is very intereresting to see the effect in real life.

Mini truss

G'day people Time to show me if Instructables lives up to its name I need to come up with a very easy and fast way to build a minituare truss (picture of truss attached). It basically consists of two aluminum face sheets, that sandwich a network of drinking straws. The drinking straws are arranged in such a way that they form little pyramids (take a look at the picture for it to be clearer). My issue is that I'm working with very tight dimensional restrictions. The 2nd picture shows the dimensions of the top and bottom face sheets. The drinking straws are 3mm in diameter. The edges of the "pyramids"  must form an angle of 30, 45 or 60 degrees with the horizontal plane. The current method I'm using to make these trusses takes about 5 - 6 hours.  I need something that could take less than an hour. Also, the straws are glued to the face sheets with a small glue gun, but this leaves a lot of "glue residue" around the straws. If you have any better ideas.... what say you?!! edit: I forgot to mention that money is not really much of an issue, so if you suggest I need some equipment or something of the sort that would be rather expensive, I will seriosuly consider it!

Growing Grub

Here in France we suffer a lot with doryphores (Colorado Beetle). For the last few years I have grown my potatoes in straw which does seem to have reduced the number of beetles I've had to put up with. 1) A week or so before planting time (or, if you want to try and conserve water do this in winter), break open a few bales of straw and lay the wedges - tightly together - over your spud patch. 2) Soak for several days until saturated. (if doing over winter then forget this stage. The rain will do it for you) 3) Lay seed spuds over the soaked wedges and cover with loose straw. As the spuds grow just "earth up" with more loose straw 4) From time to time check the bottom is still damp. Water if required. I find that I rarely have to water 5)To harvest, or if you want just a few New Spuds, lift the loose straw and take what is wanted. 6) After all the spuds have been harvested you can either leave the straw in situ and re-use next year, dig it into the ground or move to a manure/compost heap to finish rotting down. Sorry I haven't got any pics. I didn't think of taking any as I've used this method for a few years and I've also broken my camera when I had a fall. Haz

How can I float a small ring magnet? Answered

I am creating a fluid level indicator for my automated drink mixer and need either an alternate solution or an item that can float a small ring magnet. Currently, my idea is to sink a reed switch into a straw, with a ring magnet around the straw.  Once the magnet floats down to the reed switch, it lights up the indicator that the alcohol is (almost) gone. Unfortunately, I cannot find a durable non-toxic way to make the magnet float.  I've done several searches and the closest matches I've found are fishing tackle, which I'm not sure would work all that well.  I've found manufactured devices, but $30 per bottle is a bit much to spend.  I'd like to keep it to under $5 per bottle.

How to make small scale hempcrete?

Ideas for "Consuming" Outdated LEDs

Hello all! I have many of Cheap and Outdated LEDs (In thousands) lying around. These were purchased long time ago (2003~2005) when luxeon Stars were hardly available and costed Rs 1000 a piece. These LEDs are- 5mm 20 deg White ~100pc 4.8mm "Straw Hat" Low dome 100 deg White.~ Many 1)Both of them are rated at 20ma, 3.2 volts. 2) Straw hats are twice as better (Life, brightness, Even-ness) than low beam angle 5mm ones 3)I learnt the hard way using these in many precious projects. Now I know very well that 5mm LEDs dim considerably even at 20ma after a year intermittent use. I had made 36-LED matrixes (about 2 watts) with good spacing between LEDs, Legs uncut still went dim after a year. 4)There is a huge variation in Tint, Voltage and output of these. Straw hats are better , but still 5)These are not entirely Cheap in money per-se. Costed 3 Rs per piece. Today a reasonable spec Chinese 350ma Star costs 40 a piece. If we consider a bunch of 18 of these to make that wattage, They add up to Rs 55 6)Advices to throw them in the bin/ Donating/ smashing with bulldozers./ Overvoltage Fun etc are not my idea. 7)Don't want to spend tremendous time/energy/money than they're worth.

Nesting Sparrows Journal

Hello all, Ive got some House Sparrows nesting in my yard, right next to my window. I know their just boring 'ol sparrows, but their still fasinating to study. Anyway, I plan on making a journal of sorts for their nest and such. I hope to be able to update it every other day or so. If you have any questions or comments please ask! I will get a photo as soon As I can. I will keep this up to date as best I can. Thanks! Anyway... April 1st-5th: Sparrows in and out, they seem to like it. April 6th: Sparrows begin filling nest box with straw. April 7-13th: Sparrow stuffing box with straw any hay. Constantly in the yard. April 14th: Frequently in and out of nest box, almost always one bird inside at all times April 15th: Lining of the nest! A number of feathers have been added to the now bowl shaped interior. Male and female always close by. April 16th - 20th: More nest lining, though they seem to be not as active as they were when they were filling the nest box with straw. April 21st: The sparrows have found a liking for plastic packaging, and have added a fair bit to the box. April 22nd: Their plastic taste continues with the addition of a plastic bag. Its getting really cramped inside, though there is a nice bowl shape inside now. April 23rd-26th: Finished lining, the sparrows seem to be spending their down time in a nearby tree, soaking up the sun.

Ring-A-Day

This has been going all year, but I just came across it via NOTCOT:   Colleen Baran's Ring a Day project is one surprisingly creative treat after another. The project is about ideas and fun more then commercial work. It's about the idea that feels most exciting that day. Some rings will be ephemeral and temporary made of fragile materials. Others will be carefully crafted for durability and meant for long term daily wear. These will be coming later in the year. They are experiments in line, shape & color. An exploration of ideas like a daily sketchbook. Some are quite serious and carefully planned, some are a little silly, some will take a couple minutes, others many, many hours. Most (so far) are made of recycled or alternative materials as diverse as felt, false eyelashes, cucumber facemasks, lipstick, repurposed elastic bands, twist ties, straws and tinfoil with carob. The rings are documented on Flickr - my favourite so far is the straw ring illustrated below.

Ice Rink Leveling?

Looking for anyone's practical experience here. I have made backyard rink last 3-4 yr, now upgrade to Nice Rink liner. Holding water never a problem, many in Northeast last yr had limited time due to warm winter. My rink is triangle shape with legs 20x30. Slope on one side  goes from 1" to 7" or so, average ice thickness is 3-4". Part of rink over brick patio block. Use wood 2x6-2x10 borders. Was thinking of putting hay/straw under liner in the deep sections to reduce volume/depth so I can freeze solid and not have water layer under the ice. Or do you think the trapped air (under liner) will warm and work against this. I would think enough straw would not fully compress and help reduce water level, but then interface between liner and actual ground will have a lot of air space. Got a few months to think on this, my season is late Dec-mid Feb.
