For the Tornado he used two soda bottles. There are only four very easy steps to make this science project. He punched a hole in both lids. He then lined up the lids, making sure the holes line up and glued them together. He filled ¾ of the way with water and used some food coloring to color the water. The last step was to screw both bottles to the lids and let the water flow from the top bottle to the empty bottle below.
For the Slime he used borax laundry detergent, Elmer’s glue and water.
