15: go google a weird space fact and tell us what it is!
In space the skin on your feet peels off!
This is a pretty gross fact but in the micro-gravity environment,
astronauts are not using their feet to walk. Therefore the skin on their
feet starts to soften and flakes off. As laundry facilities do not
exist in space, astronauts will wear the same underwear and socks for a
few days. Those socks then need to be taken off very gently. If not
those dead skin cells will float around in the weightless environment.
I like weird stuff :F
Also, have a fascinating video!
