Depending on the variety, a condom can hold up to 7 gallons of liquid!

Depending on the size and type of condom being used (lubricated, unlubricated, thin, regular, standard size, magnum, etc.) a condom can carry between 2 ½ gallons to 7 gallons of liquid.

To put this into perspective, the average ejaculation produces about half an ounce of fluid. At 128 ounces in a gallon, the largest condoms can hold 1,792 times the amount of fluid that it actually needs to.

This was all discovered as part of an experiment that you could do at home. Check out how it was done here.
