This quick tip is and easy and effective way to tell if an egg is boiled by spinning it.
Place the egg in a cotton fabric. This is mainly for "egg safety" and for better results if you trying to find a hard boiled egg.
Now try to spin it.
Non boiled eggs are resist to spin. This caused not by the fabric fraction by the inertia phenomenon of the egg itself.
In the other hand boiled eggs are spinning since the are solid and no inertia is caused.
Hope you like it (and hopefully not knowing it yet!)

This makes for a good science experiment -- explain to your child or student what's going on inside the unboiled egg with respect to inertia and the spinning contents.
