This weekend Ezra and I had a lot of fun making this Homemade Marshmallow Catapult. We just got our hands on the NEW Science & Stuff book by Guinness Word Records and Ezra could not wait to get started. For Christmas this year he had Guinness World Records books on his wish list, so when I let him know that we were going to be getting this Science & Stuff book in the mail he was ecstatic!
Creating something with someone is so great for growing a bond and strengthening a relationship. I love that this book is filled with tons of facts and stories but also offers different science experiments that you can do together as a family. Along with this DIY Homemade Marshmallow Catapult you can also find 9 other experiments like; make your own lemon battery or a Mentos and soda rocket car to name a couple.

- Bull-dog Clips
- Oversized Popsicles
- Popsicle sticks
- Hot glue gun
- Bottle Caps
- Safety Glasses
DIY Marshmallow Catapult Instructions:
- Start by taking four oversized popsicle sticks and creating a square for the base. Hot glue gun together at the corners.
- Take three more oversized popsicle sticks and glue those ends three in a row in the centre of the square.
- Grab four more oversized popsicle sticks. Cut the ends so that one side on each stick has a flat end, leaving one rounded.
- Use two of these sticks on the end of the bull-dog clip to create extended arms. Hot glue gun them together so that the metal clips are sandwiched in between the oversized popsicle sticks. Repeat on the other arm of the bull-dog clip. (*tip: use a lot of glue along the whole base of the sticks to make sure it holds well)
- Take one side of the just created extended arms and hot glue gun it to the middle of the base that you initially created.
- Cut two regular popsicle sticks and cut the ends so that one side on each stick has a flat end, leaving one rounded. These will be used to create the triangle sides.
- Form a triangle with three popsicle sticks, one end will stick out farther. Use the cut popsicle stick within this triangle, see image below.
- Once both triangles are made glue them to the sides of the middle oversized popsicle stick to run along the launcher.
- After both of these are in place cut another popsicle stick the the distance of the two triangles. This will be used to stop the catapult arm when firing.
- Hold down the catapult arm to the base and hot glue gun the cut popsicle stick to the two triangles, from one side to the next.
- A little ways from the top of the catapult arm hot glue gun the bottle cap lid. Leave enough space for your finger to comfortably hold down the catapult.
- Now grab your marshmallows, find a target and have fun!
Ezra and I got to build the catapult together which was such great one-on-one time together. He loved doing all the hot glue gunning. This experiment is very kid friendly and they will have even more fun playing with it knowing they put the time and energy into building it.
We got this experiment from the NEW Science & Stuff book from Guinness World Records. There are nine more experiments inside along with a whole bunch of other interesting and engaging information. Get more information on the book and where you can find it on the Guinness World Records Science & Stuff website.
