Prima Arta - Gallium 99.99% Pure - 20g by Prima Arta electron

Very cool to play with. However I lived and learned to not play with this over carpet! If some of the gallium drops onto the carpet in liquid form, it will be tough to get out. I dropped some at work on berber carpet and a co-worker was able to get it out with the following process. 1. Put very hot water into a glass or ceramic mug (coffee mugs work great as the bottom has a concave area). Place over the gallium in carpet. 2. Let stand for 10-15 minutes. 3. Use a toothpick (coworker cut coffee stir straws at a sharp angle to get a fine, stiff point) to kind of scrape/pick at the metal. The little bits you pick at will gradually form a ball *on top* of the carpet fibers. This is key. 4. Once all the metal is extracted from the carpet fibers and the ball is on top, use a thin plastic spoon to "roll" the half molten ball into. 5. You should have no more visible metal in your carpet! May need to spot clean as normal for staining. Also, not sure if this would work but I don't see why it wouldn't, you could possibly use solder wick or a solder sucker, both found on amazon.

I bought this gallium about a month or 2 ago I bought 40 grams when I received it I though I'd weigh it but when I did my scale said i only have 10 grams I then contacted the company saying that I only received 10 grams and then forgot about it two weeks later I got the rest of the gallium. I am 15 and I love chemistry and science. Gallium is a very interesting metal it melts at around 85 degrees Fahrenheit or 29 degrees Celsius. When melted it can be put on to aluminum to degrade the aluminum's structural integrity so you can punch through it. You can also cast from a mold but this metal sticks to things when it hardens so I dont recommend casting it in something that you wont be able to smash or cut to get the gallium out of (you can also use silicon molds). Also DO NOT and I mean do not store the gallium in glass. When gallium hardens it expands and can break the glass. Also gallium is non toxic but like other metals use common sense and dont eat it or inject it. Another thing is it is very messy if you hold it (solid or liquid) it leaves a dark grey powder on your hands that is hard to get off. Also try your best not to spill it. Also I've seen people have been having problems getting the gallium out of the container the way you get it out is to take a glass of water and stick it in the microwave for 1 min then hold the gallium in the water and make sure you hold down the lid because the hot water will cause steam to form in the tube and may cause it to pop open. Once its melted you can cast it into almost anything. They for it to harden faster you can stick it in the freezer for around 45 mins. Though every time you melt it you will lose a very small amount of gallium due to oxidation. Also just so you know the dencity of gallium is 5.91 grams per cubic centimeter so if you buy 20 grams you get around 3.3 cubic centimeters of gallium. The picture below is a picture of my 40 gram ingot of gallium

you will need to heat it up first to get it out of the freaking tube. it will melt in your hands if you are out in the sun on a 100 degree day. but it takes some work. ooh and once melted, if you put it back into the tube. omg. brain damage. you must heat it up again to get it back out. a good hot hair dryer will do the job. i only got the oust side layer to melt. it just looked like silver pimples popping as you roll the nugget in your hand.

Well its gallium and does melt but I have nothing to do with it and like many people I fear that if I handle it to much I will get some bad health problems down the road from either the ga or some other elements alloyed with it that leached out, and that scientists discovered it wasn't as safe as they thought it would be. Its a steep price including the shipping and a much smaller quantity than shown in the pic. I really feel that if like me, you wanted it as a novelty item then you would be better off saving you money for something else since I hardly use the gallium. It does get on your hands as thin grey layer and can take a wile to melt if it froze all the way. If you want gallium the by all means buy some from these people but think to your self if you really want it first.

I bought this for my kids after seeing a you tube on it. It's really cool. My 13 year old was most interested in it. He plays with it more than than anyone else in the house. What I didn't like about it is that 1 )it came in a plastic container and it was hard to get out. Once I got it out it was fine. I put it in a different container.2) It takes a little longer than I would think for it to warm up. 3) It leaves a black residue on your hands. So, if you know all of that its fine. What I did like is that its really interesting and the kids love it!

Great product. Just a warning to anyone who buys it; it is a metal and it does oxidise on your hands. This means it leaves some grey marks on the skin. Don't worry! These easily come off with simple soap and water. And also a tip, it takes a while to melt and to re-solidify due to the specific latent heat (ie physics stuff) But if you're a wee bit patient this stuff is brilliant!

This definitely constitutes as a fun and unique present. It arrived within a week, to my complete surprise, and did arrive in a different storage container than pictured like other customers said. Mine arrived in what looks like a plastic test tube with a lid on it. The entire container/sample is about two inches long, so it is small. The sample also won't just immediately melt in your hand; you need to warm it up considerably. What I did was heated a mug of water for a minute and held the sample in there, in the test tube, for about 30 seconds. That did the trick and it was then completely liquified.

This is SO COOL! My kids played with this for hours, and then used it for a science project. It got them interested in the elements and periodic table. I bought a book (see link below) on the periodic table to go with it and my 8 year old loves the book, too! It looks very similar to mercury but it hardens when you are not playing with it. Some got on my tile floor and when I scraped it off, it looked like silver flakes. Here is the book: http://www.amazon.com/gp/product/1579128955?redirect=true&ref_=cm_cr_ryp_prd_ttl_sol_141
