For a while now, I've wanted to try mixing gallium and indium metal together by shoving them into each other, where something interesting should happen.
More specifically, they form an alloy that's liquid at room temperature, and when mixed with tin, they form something called Galinstan. Galinstan is a lot like mercury, and is often used as a less toxic replacement, in things like thermometers.

For as long as I can remember, I've always been fascinated by liquid nitrogen and I've always wanted to be able to make it myself, but I never did because it just seemed too difficult. Recently though, for some unknown reason, I felt that I was ready to try doing it, despite having basically no experience with stuff like this, and I decided to just go for it.

For this one, I'm going to try to synthesize a bouncy ball. Basically I'm making something called Thiokol rubber, and hopefully as a ball, it'll be bouncy.
I have this little tube, that been been sitting on my desk for over a month. What's inside is potassium metal, that looks gross and dirty because it's so reactive, and it's soft like weird butter.
A while ago I made some perfectly clear ice using a cooler, and I thought it was pretty cool. There were a lot of comments though, that said I could have saved a lot of time and effort, by just boiling the water, so I've decided to test that out.
This is just a bunch of regular nails and I really want to try and liquefy them. Normally this would be pretty difficult, but I bought this little induction heater on eBay, which should be able to do it.
For a while now, I've been wanting to make an explosive liquid metal, and all I need is some sodium and some potassium. And after mixing them together, I eventually had a perfect liquid metal ball. Finally, I pulled some of it out with a syringe, because there's just one thing I have to try.
