"Well Isn't That Wizard?"

(You have to imagine Catherine Tate as Donna Noble saying the title for it to be funny.)

Here's a cute little experiment you can do at home. Except it's not an experiment at all. A trick? A stunt? An amusement.

Take a fairly tight and springy rubber band and wind it back and forth around something (like a half-empty bag of frozen veggies). Allow the rubber band to freeze.

I have no idea how long it takes to freeze, sorry.

Once the rubber band is frozen, take the rubber band off the veggie bag and drop the band onto the counter.

And watch as the rubber band flops around like a living worm for a few moments as it thaws and pulls itself back into its resting state. Good times! I'm easily amused.

I wonder if this would work with a bungee cord as well. Might work as a prop in a low budget 'Attack of the Worms' film...
