Step-by-step tutorial
- Step 1- Gather your materials.  
- Step 2- Carefully cut out the bottom of the plastic cup. If needed, your grownup assistant can do this for you!  
- Step 3- Leaving the balloon deflated, tie a knot to close the opening. Then, cut about a quarter inch off the top of the balloon to create a large opening.  
- Step 4- Stretch the balloon over the bottom opening of the plastic cup. Give the knot a tug to make sure it is on securely.  
- Final result!- Now your marshmallow shooter is ready! Load up the marshmallows and give the balloon a tug to see how far they go!
