String or yarn
Tape ($1 store duct tape worked best)
Two chairs or two places to tie string between
First, cut off the bendy end of the straw so you have just a straight piece left
Take your string or yarn and thread the large-eyed needle. Place the needle in the tip of the straw. Use the bamboo skewer to push the needle down the straw until it comes out the other end.
|The bamboo skewer is the KEY to getting this floppy yarn through the straw. It will save you much frustration.|
Now you want to tie your yarn off in two place and make sure the string is very taut between the two points. We used our stairs and a door knob.
You can also use two chairs, or two objects outside if the weather is nice. The two points we selected also had different elevations. The stairs connection was higher than the door knob finish line.
Now came the part where we blow up our first balloon
|It's important to color coordinate your balloon with your current outfit, right?|
Make sure the balloon is facing the direction you want to launch it, with the "exhaust" blower in the back and the round part of the balloon facing forward. After that... you are ready to activate the launch sequence.... 3...2...1...
|"Huston, we are a GO for blast off"|
When it reaches the end of it's ride, it will look floppy and sad. But the nice thing is the $1 store duct tape holds onto the balloon in the right place and you are ready to launch again
Well you can't have three kids and only one balloon rocket. So we set up another launching path
|We made track #2 at a lower elevation so we could have rocket RACES!|
My middle child thought that a larger balloon would travel faster. We found out that a larger balloon would have traveled farther (if our string had been longer) but it launched at the same speed as the purple balloon. The only bonus was that the pink balloon would reach the end of the track and still have some air left over. It would spin around and make that satisfying raspberry sound, which spurned on even more giggles. After that we had an afternoon of zipping and racing. It was a rocket balloon extravaganza!
Ready, set, GO!
