| − | #Gather the necessary materials. For each basic square you will use five popsicle sticks and wood glue. Each layer of the tower will be made up of four basic squares, so each layer will use 20 popsicle sticks. The number of layers you want to make will determine how many total sticks you will need.<ref>http://philliphansel.org/popsicletower/</ref> | + | #Gather the necessary materials.

| − | #Arrange four popsicle sticks together in a square. Lay out four popsicle sticks in a square with the horizontal sticks on the bottom and the vertical sticks laying on top. You want the sticks to be evenly spaced apart so they make a perfect square. Using one popsicle stick as a measuring device, make sure each stick is one “popsicle stick width” from the edge.<ref> http://philliphansel.org/popsicletower/ </ref> | + | #Arrange four popsicle sticks together in a square.

Repeat this with the other side of the popsicle stick and then two more times with the other vertical stick. At this point, you should have a basic four popsicle stick square glued together.<ref> http://philliphansel.org/popsicletower/</ref> | + | #Glue each piece together.

#Wait for the glue to dry. Before continuing on to the next step, you want to let the glue dry. Follow the instructions listed on the bottle of glue you are using. The glue does not need to be completely dry, but you want to make sure it has set enough that the sticks will not move as you handle the square. | #Wait for the glue to dry.

| − | #Glue a cross brace diagonally across the square. Place a popsicle stick diagonally on the “inside” of the square. The “inside” means the brace will be between the two vertical sticks and glued to the horizontal sticks. Place a small dab of glue at each end and glue the brace in place. The brace is essential stabilizing the structure and allowing it to hold more weight.<ref | + | #Glue a cross brace diagonally across the square.
