It's the 'T' Puzzle! Make a tiny 'T' Puzzle for your purse, pocket etc. Or you can make a larger one for the home! The 'T' Puzzle is just a big T with diagonal cuts in it.
You will need:
Clay (I use Sculpy)
Rolling pin (Meddle wotterbottle or other round, heavy objects will work fine)
Step 1: Forming the "T"
Sandwich a piece of clay (you can really do any size you want) between two pieces of wax paper. (This is to protect any surfaces from getting stained) Roll out the clay so that it is in a rectangular shape about 1/4 of an inch thick.
Cut out a 'T' shape from the rectangular clay.
Step 2: Cut pieces and Bake
Cut the 'T' diagonally just like the picture.
Bake the clay according to the directions on the box you got it in.
Step 3: Solve it!
Mix up all the pieces and give to a friend to solve. It sure will confuse them!
Have fun making your friends mad! :P
