I recognised the behaviour as similar to that of the common slime project based on PVA glue and borax, and since I had the materials on hand I decided to make some and test it. Note that I don't actually recommend hitting your hand with a hammer whether you have a protective gel there or not. The characteristic that matters here is that the gel is non-Newtonian. Is has a very odd characteristic that it will flow like liquid, but immediately go solid when compressed and even crack. It has a very long history as a kids toy and there are thousands of videos about it on the 'net. This is one of very few that involve a hammer though. You can buy the materials needed to make this from eBay and other sources. The main thing to do is make sure you get real Borax (Sodium Tetraborate Decahydrate) and the common washable PVA glue. I'd actually recommend you stock up on Borax in case they try to clamp down on it again. There's a certain irony that after the anti-Borax scaremongering there are slime videos showing the use of "safer" materials which completely lack the inherently preserving nature of boron. The combination of moist gel and organic materials in some of them may actually pose a real health risk to kids playing with it. I'm not sure how long this stuff will last. I'd guess that the high presence of boron in the gel will make it relatively resistant to mould and bacteria. It does dry out if left in open air, so is best stored in a bag between uses. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
