A fragile egg is actually pretty tough. See if you can put an egg in one hand and tighten your grip to the point of smashing it. Make sure you're not wearing a ring which might cause too much pressure on a small area, and be sure to do this over a sink just in case you are strong enough!

The design of an egg makes the pressure spread over a large area and not a small spot, which is how you normally crack an egg.

So, give it a try Hercules and test your strength!
