Ok, I guess I will have to come up with a better one ! :-)

Try this... take a dry erase board and derive maxwells equations from first principles. When done , take the dry erase eraser and erase the board. While still holding the eraser touch something electricialy grounded. The spark you see represents the electrostatic energy which was holding...

First off, I may or may not know the correct answer to this one... Here it is.. I have a set of say 100 small perminent magnets which are randomly oriented in space. I also have an empty burlap sack. I grab each of the magnets one at a time and throw each one into the bag until all...

I don't really understand about catalysts... I am thinking about an exothermic reaction in the presance of a catalyst. My understanding was that the catalyst lowers the energy threshold for the reactants to commence reacting. ( I think that was gotten from shell theory and bonding energys )...
