Introduction:
Marshmallow catapults are a popular and entertaining activity for kids and adults alike, allowing you to have fun while learning about physics and engineering concepts. In this article, we will explore three different ways to make a marshmallow catapult using simple materials found at home or in the classroom.
1. Popsicle Stick Catapult:
Materials:
– 7 popsicle sticks
– Rubber bands
– A plastic spoon or bottle cap
Instructions:
1. Stack five popsicle sticks together and secure them with a rubber band on both ends.
2. Slide one popsicle stick below the stack, positioning it in the middle of the bundle.
3. Place the other popsicle stick on top of the previous one, perpendicular to the bundle, and secure them with a rubber band in a criss-cross pattern to create tension.
4. Attach the plastic spoon or bottle cap to the end of the top popsicle stick using a rubber band.
5. Insert a marshmallow into the spoon or bottle cap, pull back, and launch!
2. Plastic Cup Catapult:
Materials:
– A plastic cup
– Duct tape or masking tape
– A rubber band
– A binder clip or clothespin
Instructions:
1. Cut a slit into each side of the cup, approximately 1 inch (2.5 cm) down from the rim.
2. Securely loop the rubber band through the slits.
3. Tape the binder clip or clothespin to the bottom of the cup, ensuring its opening faces away from the cup.
4. Place your marshmallow launcher onto a flat surface, such as a table.
5. Insert a marshmallow into the cup, pull back on the rubber band, and release to launch!
3. Cardboard Tube Catapult:
Materials:
– A cardboard tube (e.g., toilet paper tube)
– Scissors
– A plastic spoon or rubber band
– Duct tape or masking tape
– A small wooden block or a stack of coins
Instructions:
1. Cut a slit halfway down one side of the cardboard tube.
2. Slide the handle of the plastic spoon or the rubber band into the slit, securing it with duct tape or masking tape.
3. Use the wooden block or a stack of coins to elevate one end of the cardboard tube, creating an angle for launching.
4. Place the catapult onto a flat surface, ensuring that the elevated end faces away from you.
5. Insert a marshmallow into the spoon or wrap it with the rubber band, pull back, and release to launch your marshmallow!
Conclusion:
Whichever method you choose, building and using a marshmallow catapult is a fun and educational activity. You can experiment with different designs, materials, and angles to improve your launching distance and accuracy. Gather some friends and have a friendly marshmallow-launching competition!
