Give My Creature LIFE
Or at least make it spin a little. A simple motor: battery, magnet and wire.
Magnetic field sees a changing current and that results in a force, which gives you a motor. Quite similar to the Faraday motor, but then, he was allowed to play with mercury (and he never wore a bike helmet, either)
Update: Give MY creature life. Built one myself this afternoon, and even figured out how to upload it to YouTube. She may not look as pretty as these other motors, but she loves to spin. (First attempt didn’t go so well, but I found lighter wire that was still stiff)

Chladni Plate using salt.
You might want to turn the volume down — it starts to get pretty annoying about halfway through, as the frequency goes up, and you may be summoning all the dogs in the area.
Some Chladni solutions for a plate constrained at the center.
Can't . . . Avoid . . . Collision
Remember the conservation-of-momentum problem you did in 1st semester physics, where the projectile breaks into two pieces at the apex of its flight? Now multiply by Avogadro’s number (and then an additional order of magnitude or more)
Momentum’s conserved, even in slo-mo.

And just like that when I had given up all hope,
I said nope, there’s just one way to find that slope.
And so now I, I will derive.
Find the derivative of x position with respect to time.
It’s as easy as can be, just have to take dx/dt.
I will derive, I will derive. Hey, hey!
