Using a ruler, stack 8 nuts with bolts screwed on the end.
Prior to game start, place the nuts on the bolts and lay them on the ruler so that they can freely roll off the end.
Place a hand foul line on the ruler.
When the clock starts, the player picks up the ruler and attempts to stack the 8 nut/bolt pairs vertically without dropping anything.
If any nut/bolt pair (other than the first one placed) touches the table, the game is over.
To complete the game, stack the 8 nut/bolt pairs vertically and remove the ruler. The stack must remain standing for 3 seconds within the 60-second time limit.REQUIRED ITEMS
