The other day in physics, my teacher whipped out one of those ball things and started to demonstrate how energy moves from one object to the other. I thought that that thing was so cool! one of these days i'm just going to buy one and start it and see how long it takes for it to stop.
Is there something you like that really has no reason, but just makes you smile?

jeff wants to be smart and let you know it's a newton's cradle.
okay, i'll let him think he's smart!
(i didn't know that! Thanks jeff!)
Ummm...I'm not sure, but I know I've always wanted one of those ball things. :)
mel used to have a little cylinder that dripped black oil inside water, i think, and ran down a twisty trail into the bottom. i've always wanted one. and jeff has a time machine that would be cool.
I forgot about that oil thing Mel had...that was fun...=)
