Juggling with knives but I don't dare to, too much of a risk to hurt myself!
Here is another fun experiment you can do with mercury, turn it into a "beating heart" ^^ It's a principle of redox chemistry the mercury is oxidised and decreases surface tension going flat, when it comes into contact with the iron nail it undergoes a reduction reaction and surface tension increases and it contracts back and the Process repeats.
Edit - I always enjoyed using liquid nitrogen in the lab, always made me feel like a kid. Apart from the time the person working next to me managed to poorly seal his equipment which was supposed to be under vacuum, ended up with a nice build up of liquid oxygen, Had me worried for a moment..

either:
or
Fire in to some degree and ofc roll down the street with a tank would be a win aswell Ow and also fireworks
Ever since I was a kid, I was fascinated by liquid nitrogen and liquid mercury. I would love to go to town with those, assuming no one was in danger and/or I had invincibility (make it happen, Jesus). I also have played a lot of jRPGs and really want to play with katanas, kunai, and various other swords. Also. Outer space.
Speaking of liquid nitrogen, I want to find a spider web, spray it, and make it solid/fragile. Assuming you can just spray things and don't need to submerge them for long. I don't know how liquid nitrogen works...
