Why it helps

This exciting activity introduces your child to the power of air and movement. Building the boat requires careful bilateral hand use and coordination. It also works on mouth muscles as they blow to inflate the balloon. Your child will love seeing how their hard work creates motion!

Steps

Fill the biggest foil pan you have about halfway with cool water and set it on a flat table.
Tear off a sheet of foil about the size of a piece of paper and fold it in half. Help your child fold up all four edges about an inch and pinch the corners to make a flat-bottomed boat.
Slide the neck of a balloon over one end of a straw. Wrap masking tape tightly around the neck so no air leaks out.
Tape the straw along the floor of the boat so the balloon sits near the front and the open end of the straw sticks out just past the back edge.
Ask your child to blow through the straw to fill the balloon, then pinch the straw end shut.
Set the boat on the water at one end of the pan with the straw pointing toward the near wall.
Let go of the straw and watch the escaping air push the boat across the water.
Blow up the balloon again for another ride. If water splashes in, fold the sides of the boat a little higher.

Safety tip: Stay close during water play and wipe up spills. Balloons and popped balloon pieces are a choking risk, so an adult keeps loose balloons and picks up any pieces right away.

Make it easier

Blow up the balloon for your child and let them pinch the straw and launch the boat.
Use a bendy straw so the open end can point straight back toward the water.
Stretch the balloon a few times before slipping it over the straw so it goes on more easily.

Make it harder

Race two boats side by side in a bigger tub of water.
Try a big breath and a small breath, and compare how far the boat goes each time.
Fold boats from foil in different shapes and test which one travels farthest.

What to watch for

Notice how your child holds the straw while stretching the balloon over it. One hand steadies while the other pulls.
Watch whether your child can blow out through the straw without sucking air back in. Long, slow breaths fill the balloon best.
If the squeal of escaping air or the chance of a pop worries your child, use a half-filled balloon and launch it together.

Where this helps in daily life

Holding one thing steady while the other hand stretches and wraps is the same teamwork kids use to put a hair tie on a ponytail, pull a sock over a heel, and tape a gift closed.
