I just read this on the panel of 'Useless Knowledge' on the right side of my blog:
A ball of glass will bounce higher than a ball of rubber. A ball of solid steel will bounce higher than one made entirely of glass.Wow... Imagine a bouncing ball of glass... :O
Kids, do not try this at home! Adults, if you intend to try this, do remember that a ball of glass will shatter when dropped on/thrown against most surfaces. A ball of solid steel, meanwhile, is likely to shatter everything else. A ball of rubber can be dropped/thrown
quite safely. Do note though, that I shall not be responsible for shattered chandeliers, smashed glasses (drinking glasses, reading glasses, glass balls, etc...), holes in windows, and any other possible damages resulting directly or indirectly from dropping or throwing a rubber ball.
Ok, now you can go ahead and experiment.
Go on!
