I can think of two things I want to do before I die.
#1
1) Glue chess pieces to chessboard and attach arm strap to bottom
2) Sneak this onto a Rollercoaster that takes pictures during the ride. (Sit next to a friend)
3) Have both you and you and your friend look inquisitively at the chess board during the ride. (Bonus points if one of you is rubbing your chin and manages to hold a perplexed look)
4) Awesomeness ensued! Really, what would you think if you saw a Rollercoaster photo where everyone is screaming except two people in the middle who look... Well... I think you get the point. :p
#2
1) Get an old/unwanted/leaking canoe.
2) Attach wheels to the bottom, a primitive pedal steering system to the front, motor at the back.
3) Put on life jackets, fishingwear, and load canoe with tackle and fishing supplies.
4) Get a friend and two paddles, then take it for a drive... Bonus points if you and your friend make paddling motions while going down the road.
