So I got this bottle of blue goo, and I immediately thought, "Repulsion Gel in real life :D." It's not going to make you jump 10 feet in the air, but it is hard to hold in your hand because it'll fling right out. It also looks a bunch like the Gel too and seems to have the same consistency (but less sticky, messy, and fluidy).
I'll post pics and a video soon.
