BLUE Space Sand: 1lb BULK: Hydrophobic in USA

BLUE Space Sand: 1lb BULK: Hydrophobic in USA - Space Sand truly is the closest thing to soil from Mars that most of us will ever experience! The soil on Mars is very similar to Space Sand in terms of properties and color. This unbelievable sand will not get wet and can be formed into shapes under water. Remove it from the water with a teaspoon and watch in amazement as it miraculously turns to completely dry sand! There are many things you can do with Space Sand from making a sand raft to observing the silvery barrier that forms between the sand and the water as you explore its many uses from cleaning oil spills to improving the growth of plants. The informative information sheet explains it all and outlines tons of other fun experiments to do with Space Sand! We stock six colors of sand and sell it in bulk. Ages 4 and up.

This is some very cool sand! . This stuff is great fun, especially for kids. It never fails to amaze when you stick your hand into a bowl of water and scoop some up from the bottom, only to have it come up from the water's surface bone dry!

This would make a great school science fair presentation, both for it's entertainment value and it's practical applications, such as cleaning oil spills and helping to grow crops in dry regions.

By the way, it's also totally re-usable. Once you are done playing with it, dump out the water and stick it in a zip-lock bag! I'm not sure if the sand's hydrophobic coating ever wears off, but I have gotten plenty of use out of the small quantity I ordered.

As always received this product from Amazon promptly and exactly as described.

BLUE Space Sand: 1lb BULK: Hydrophobic Reviews
Bought for school use . I use this as a neat hands-on lesson about the terms 'hydrophobic' and 'hydrophilic' (use regular sand for that one). The kids LOVE it. This particular brand is very fine, so there are some particles that will float but overall it works just like any other brand I've used.
