AWESOME density fact

just last week I was at this party and I was talking to this chick and I told her 'Hey baby, did you know the density of aluminum is 2.7 g/mL and so it will sink in water?' and she was all 'That's amazing! I want you so bad!' and she was, like all over me that night. Because it IS awesome

Here's anoher for her sister; Water get's less dense as it freezes allowing it to float on water.
