Depends on what you mean by "bounce".  If you want to fake it a bit, you can just have the other sprite change direction by 180 degrees, maybe add in a little random variation just to keep it interesting.  It won't look very realistic at low angles but it might do the trick.

I've got an idea on how to do that:
1) Drag on an "If Green Flag clicked" block and then you snap on a
"Forever" block.
2) Drag an "if" block into the forever block and then drag a "if touching color {}" block. Put the color of that sort of "object".
3) Then put on a "go to x: y:" block and snap on two "pick random from whatever to whatever" block. It's pretty straitforward from there. Good luck with the programming!

Oh, ok. So you cant't use colors.   Hmm... *light bulb* I got it! You just make the color in the script thing gray, or black or maybe even white if the backround is like black or something.

ok, and with colors how do i should do it?

There are multiple ways to go about it, some rather simple and some more complex. If you have flat, 90 degree walls and floors, you could make a sensor sprite to detect what type of wall (horizontal/vertical) that the player is touching, and react accordingly.

Look at this script: here.

This uses only the sprite you're moving, no sensor sprites or sensor colors needed.
