What happens when you play Cypress Hill to a squid?
Seriously, you have to see this.
Squids don't have ears, as we know them. But it is possible to convert an audio signal into an electrical one (this is what happens when you speak into a microphone; sounds coming through speakers is the reverse). Scientists at Backyard Brains wanted to know what would happen if they hooked up an iPod Nano to a Longfin Inshore squid via a suction electrode.
It had an amazing effect on the squid's chromatophores — that is, the cells that control the colour of the squid's skin and allow it to camouflage itself.
Watch the video to see what happens.
