Explore some of the more interesting properties of air with this activity packed kit. How many breaths does it take to inflate an 2 meter (8 ft) Windbag? 70 breaths, maybe? Why even try? With a simple science secret you can amaze your students and friends by blowing up your Windbag in one breath! If you don't believe it, try this amazing science activity! Windbags are so light and strong that even the smallest scientist can demonstrate the amazing properties of air!
You want even more amazing air experiments. Try our Solar Bag! We guarantee you have never seen a Solar Bag like this! Our Solar Bag measures 15 meters (50 ft) long and 74 cm (29 in) in diameter. The thin, black plastic bag holds over 60 cubic meters (200 cubic ft) of air. Simply fill with air by running, tie off the ends, and let the solar energy of the sun heat the air inside the bag. Within minutes, the bag rises to the sky and floats like a giant science tube. Better tie it down or you'll be flying as well! We have provided 400 feet of Solar Bag String to let your Solar Bag fly high and yet still be able to bring it down when you are done with it.
The kit includes supplies for 32 students working in groups...
- 32 Windbags
- 15 meter (50 foot) long Solar Bag
- Spool of string
- Rubber bands to make Windbag structures
- Activity guide

Like all of Steve's products....this one is a home run!
Fun with air!

We used this kit as an activity at our church picnic. The kids loved them! The large size of the colored air bags made them fun to play with and to put together to make different shapes. The Solar wind bag was slightly more tricky since we started at about noon and it was already pretty warm. But they loved it nonetheless! They kept shooting at it with water guns, which cooled it down somewhat and allowed it to go down, then as it heated up it would rise once again. The space was a little too small to let it truly fly freely using the string. Overall it was a blast.
