Steps
Step #1: Up, up, and away!
Next
- Fit one straw end into the other, overlapping about ¼", and seal with tape.
- Bend one end of the straw into a "U" shape, using a piece of tape to hold it in place. (Bendy straws work well.) This is the front of your blimp.
- Trim the business card into a rudder shape and use tape to attach it to the straw end opposite the "U" shape.
- Fill one balloon with helium and attach with tape to the front of the blimp, toward the "U" shape. Don't let go!
- Add modeling clay until the blimp slowly starts sinking to the ground.
- Without ballast, the blimp will continue to rise.
