I did an experiment with a condom and seeing how much it would take before it breaks, and this is what I did till it broke:

•I could fit my whole hand in it, making a fist and putting my hand flat. (And I have pretty decent length nails)

•I put the base of the condom around the bathtub water faucet and turned on the water full blast. The condom didn't break till it was probably the size of an eggplant 😂
