Use condoms as makeshift water storage.

Condoms are incredibly elastic. As user Janis Butevics points out, you can use that to your advantage if you need a quick way to store large volumes of water. They essentially act like bladders and are capable of holding a gallon of water.

"They can also be used to protect against water, as a stretchable cover for valuable items like matches and walkie-talkies," Butevics says.
