If you checked out our Fun with Flight Kiwi Crate adventure, then you saw Travis and I made an indoor balloon rocket. We wanted a chance for a repeat outside, and decided it merited its own blog!

This time we made a few significant changes. First, we stretched our string between two fence posts, allowing for a longer space for our “rockets” to fly.

The next innovation was a wide straw (look for “milkshake straws” at the grocery store). This flies much more smoothly come time to launch! Thread the straw onto one end of your string.

Blow up a balloon – but do not knot – and tape it to the straw. Release the balloon and watch it fly.

This was just so beautiful outside in morning sunlight, too!

“3, 2, 1, Go!”
