Hello and welcome to Sci Guys, the show where we talk about the crazy, weird and wonderful stories from the science world.

I'm Corey, and as always, I'm joined by my co-hosts, Luke Cutforth and Jamp.

Hello.

Bonjour. Hello.

This week, we'll be talking about space squids and invisibility cloaks.

Space squids.

Invisibility cloaks.

Right.

Because I have this. You're stumped by invisibility cloaks we've seen that in harry potter last night last night i turned to carrie right and i said to him

in the in the seventh harry potter book it suddenly jk ronings like oh and now the invisibility cloak

is too small too small for them they have to crouch right so how big is that

sheet that three of them can all three adults can almost get under it like that's bigger than a bed

sheet he's just carrying around this like tent like invisibility tent anyway that's my tangent carry

up with your science off you go okay so I thought about it like's like it's it is too big well because like

harry wears it on his own when he's 11 yeah but then when he's 18 he can almost fit three people

under it three but when they're like they're like three 12 year olds that's got to be massive there's

gonna be too much left no when there's one when there's one harry in the library he must just be like

tripping over it yeah yeah people other people be trying the floor just goes invisible behind him

it stuff okay student out of bed students in the corridors as humans we've got a long history of

manned space exploration and an even longer history of just firing animals into space to see what

happens the bobtail squid is a tiny little cephalopod that went on a very, very big journey just because scientists were interested in its symbiotic relationship with some light-emitting bacteria. I believe in him. So this is the squid, the space squid. This is the space squid. Okay, nice. Not just one, there were three. Now, what is symbiotic or symbiote? Because I heard this word in venom. And I thought it was made up, apparently. James. I'm not a scientist. You've not heard symbiosis before? I didn't know. Did you not do high school biology? No, I did a semester of it and hated it so much. I just did physics and chemistry, so... That's... Australia is crazy. Yeah. We have to do biology. No. Oh, we don't have to do biology. Okay, Scotland. I did one semester. So, symbiosis is when you've got two animals, two organisms living in close proximity to one another.

Yes.
