Catapult Designs for Kids

easy catapult design for kidsLet’s face it, there’s something about launching stuff that never gets old. That’s because tinkering with the launching device is just plain fun. After all, it can always fling further, straighter and more efficiently. In recognition of these facts, Spaghetti Box Kids brings you these simple catapult designs for kids. Each one has its own unique features and method for transferring tension from the launch arm to the projectile. The best part- you do not need any power tools, just everyday items from around the house:

Basic Design
This design makes use of a simple fulcrum in order to achieve its launching ability. This is the perfect starter design for Pre-schoolers or anyone new to catapult making. Materials: newspaper, tablespoon, rubber band, masking tape.

Coffee Cup Design
This easy design offers an improved fulcrum for super launch power. It’s very easy to make and very few materials are needed. Possibly the best overall design when you consider simplicity next to power. Materials: coffee cup with handle, pencil, teaspoon, rubber bands, tape.

Fantastic Soda Can Design
The unique launch arm provides superior hurling power, and the weight of the soda cans provides a durable base. This is a rugged, well-designed household catapult that is a lot of fun to build. Materials: two 12 ounce pop cans (unopened), kitchen fork, rubber bands, cap from a plastic 2-liter bottle, two pencils, masking tape.

Amazing Dimple Design
All catapults have at least one thing in common: tension. The better it conforms with the overall design, the better the results. The lightweight dimple design is perfectly suited to the task. This is an excellent starter catapult and one of the easiest to make. Materials: oatmeal container, rubber bands, teaspoon.

Super Fling Design
This unique design uses the snap tension of an everyday coat hanger to achieve it’s flinging authority. If there were a distance contest among home-made catapults, this one might be the winner. Materials: wire coat hanger with cardboard tube base, stapler, scissors, business card or playing card, several hard cover books.

Egg Carton Design
This is a lightweight, chunky-grip catapult that’s fun to make and easy to use. The design is perfect for Pre-schoolers and other starter-age kids. Materials: empty egg carton, scissors, masking tape, rubber bands, teaspoon.

Brawny Launcher Design
The superior arm tension, harnessed by a pencil, gives this hurling machine its extraordinary power. Perfectly suited for launching objects clear across the room. Materials: four newspapers, assorted rubber bands, masking tape, pencil, table spoon.

Arc Tension Design
This power packed mini catapult makes elegant use of arc tension to achieve its hurling authority. The unique, economical design assures it a leading place in any catapult collection. Materials: invisible tape dispenser, cutting board, masking tape, assorted rubber bands, sheet of paper, teaspoon.

Bear Clamp Base Design
This mini catapult uses the Bear Clamp Base technique for harnessing tension. Once you grasp the powerful concept of this technique, you can apply it to countless catapult designs of your own invention. Materials: roll of tape from invisible tape dispenser, cutting board, masking tape, assorted rubber bands, twistie tie (found on loaf of bread), cotton ball, teaspoon.

Soup Can Design
This a quick and easy design advances the engineering behind the launch cup. The cup itself only takes a minute to make, but its features enable an excellent trajectory-arc from the vertical arm position. Performance is very consistent. Materials: unopened soup can, rubber bands, popsicle stick, business card (or cardboard from a cereal box), tape.

    […] Spaghetti Box Kids has a page with several catapult designs made with things you probably have at home.  These are truly suitable for all ages. Give one or two of them a try. […]

    Do you have any catapult that can be locked into place because I have a stem project to do.

    We have a Summer Science playgroup, and this is awesome! (mostly first graders!!)
    I love that you have included designs for little ones, and even took the time to add different games!!
    This is our project next week!!

    Thank you, thank you, thank you!!
