Select the following pieces to begin building a catapult made out of Legos.
Step 1: Lego Bricks Can Be Any Color for Any Part of the Catapult. Your Choice.
Place one 2 x 4 brick on the base plate. Attach two 2 x 4 bricks and place 3 rows from the other brick.
Build two columns of 2 x 2 bricks. The columns are 3 bricks high. Place 1 row from the connected 2 x 4 bricks.
Attach the arch to the columns using the corner studs. Attach two 1 x 2 bricks to the 2 x 4 bricks between the columns.
Step 4: Build the Lever.
Attach two 2 x 10 pieces by connecting a one 2 x 6 flat piece to the bottom and one 2 x 8 piece to the top. Attach a rectangle flat piece that is 4 x 6 to the top of the lever. Attach a 1 x 4 block to the last row of the 4 x 6 piece and two 1 x 2 bricks in front. This will hold the object in place before it is catapulted.
Attach a 2 stud slanted piece to hold the object in place before it is catapulted.
