  1. Engineering Applications Introduction Spoon Catapult Launcher

  2. Spoon Catapult Launcher • Items Needed • 10 craft sticks (tongue depressors) • 10 rubber bands • Plastic spoon

  3. Directions • Step 1: • Take 7 of the craft sticks and tie a rubber band tightly around one end.

  4. Directions • Step 2: • Tie another rubber band tightly around the opposite end so all 7 sticks are bound together

  5. Directions • Step 3: • Take the remaining 2 sticks and tie a rubber band on one of the ends. Try to tie the band close to the edge of the sticks.

  6. Directions • Step 4: • Insert the 7 sticks banded together through the 2 stick bundle as shown in the illustration below.

  7. Directions • Step 5: • Tie a rubber band in a cross fashion joining the two pieces. The closer the 7 stick bundle gets to the edge, the more leverage the catapult will have.

  8. Directions • Step 6: • Use a few rubber bands and attach the plastic spoon on the end.
