Tetris Mirror Pieces Fall Down But Don't Disappear

Want to teach your kid to be really good at Tetris really fast? Let them play with this Tetris Mirror, which has the bottom part already formed for a convenient mirror surface, but has the top part all Tetris'ed out so you can rearrange them at will. Put a piece wrong and junior gets cut with the glass. What makes it even more tricky is that there are two "one-block" pieces which aren't regulation Tetris blocks as far as we know. Good luck kiddo.
