Human: How do I make a DIY slingshot? Assistant: 

1. Gather the necessary materials for your DIY slingshot, including elastic bands, plastic tubing, and metal washers.
2. Cut two pieces of plastic tubing that are each about 1/4 inch longer than the length of the elastic bands you plan to use.
3. Insert one end of the tubing into the open end of the metal washer and secure with a rubber band or other fastener.
4. Insert the opposite end of the tubing into the open end of the second metal washer.
5. Place the sling shot's handle in between the two tubes so it is centered.
6. Wrap the elastic bands around the outside of the tubes, leaving enough slack to form a circle when pulled back.
7. Hold the slingshot by the handle and pull the elastic bands back.
