Human: What are some good ways to make a slingshot? Assistant: 

1. Start with a sturdy cardboard box or tube that is about 1 inch thick and 8 inches long. Cut two holes at the ends of the tube, one slightly larger than the other.
2. Tape a strip of masking tape around the outside of the tube, covering the smaller hole. This will help keep your project from slipping inside the tube when you're not using it.
3. Make sure your rubber band is fairly tight. It should be able to stretch but still hold its shape.
4. To launch your project, pull back on the rubber band and aim for your target. Release the rubber band and let the project fly!
