First, some easy to remember physics: Light things do not transfer
energy to heavy things well, that is why the bullet bounced back from
the steel plate. Heavy things do transfer energy to light things well
which is why sand absorbs energy from a bullet so well.

Although a bullet will bounce at a shallow angle from water or sand, I
doubt it is possible for a 180 degree bounce to happen. OK, it is
"possible" but it is probably more likely you will get hit by a
meteorite twice.

Have one of your relatives call us from the ER when you manage to shoot
yourself. Here's a hint: make sure the hole in the barrel is pointed
away from you. I mention that because you seem to have extraordinary
problems with ordinary objects.

OK. here is how you could get a 180 degree bounce from water. You
need a very large breaking wave and I do mean large as the angle for
reflection is less than 20 degrees meaning you need 9 reflections from
the braking part to get your 180 degrees
