Why it helps

This activity helps your child build hand strength and coordination. Squeezing a bag of air requires both hands to work together. This skill is called bilateral integration. It is important for tasks like cutting or dressing. It also teaches children about cause and effect. Seeing the paper rocket fly encourages your child to track moving objects with their eyes. This is a great way to provide heavy work for small fingers!

Steps

Cut a small rectangle of construction paper and wrap it around a straw.
Use a tiny piece of masking tape to secure the paper into a tube.
Tape one end of the tube shut to create the rocket nose.
Slide the straw into the corner of a Ziplock bag.
Seal the bag and use tape to make the opening airtight.
Place the paper rocket over the end of the straw.
Use both hands to give the bag a fast squeeze to launch the rocket!

Safety tip: Always supervise your child during play. Ensure the paper rocket is not aimed at faces or people.

Make it easier

Set the bag on the floor and let your child press it flat with both palms or a stomp of the foot.
Make the rocket for your child and let them do the launching.
Refill the bag for your child after each launch by taking off the rocket and blowing into the straw.

Make it harder

Tape a target on the wall and adjust the squeeze to hit it from different distances.
Squeeze with one hand only, then the other, and compare how far the rocket goes.
Build a second rocket with fins or a longer tube and test which one flies farther.

What to watch for

Notice how your child squeezes. A quick, firm squeeze sends the rocket far, while a slow squeeze makes it slide off the straw.
Watch whether your child's eyes follow the rocket through the air and find where it lands.
If the sudden whoosh surprises your child, start with gentle squeezes and short flights.
