Ultraviolet Crab Spider
A crab spider (misumena vatia) uses ultraviolet (UV) light to attract bees to certain flowers, from which it makes it ambush. Rather than being camouflaged, its UV patch actually shines as a beacon to the bees, thanks to their ability to see UV light (where humans cannot).Collected in Phy.si Videos Oct 24, 2010 -
Electromagnetic Spectrum Song
This song is so irritating, and is one of those songs that gets stuck in your head and you can't ever get rid of it. A bit like a tumour. But that's what's so good about it! Watch this song once or twice and you will forever know the order of waves in the electromagnetic spectrum.Collected in Phy.si Videos Nov 10, 2009
