Powers of Ten

If you haven’t seen this one, then you’ve truly missed something. Talk about putting the universe into perspective! Start with a view of the universe, then move in by degrees of ten. This will take you from on the outer edge of nowhere to deep inside the cell, ending with a look at the smallest particles known to man. Excellent trip, whether you slow it down and talk about each step or just let the kid watch it run.
