Ten Meters DIY Solar Balloon

Solar balloons are easy to build. Yet they are very rewarding and fun stuff for kids and adults.They are educational toys too.

Here is how I made a simple Ten meters Solar Balloon and used it on the beach.

All you need is some black trash bags and tape.

As air gets hot it gets less dense than colder air so it moves upward. Hot air balloons work using hot air to float. Hot air balloons use gas to make hot air.

Solar Balloons use only Sun light to make the air inside the balloon hot. The Solar Balloon is made of dark material that absorbs heat from Sun light and the air inside gets much hotter that the air outside. You can find this for yourself and make a fun educational experiment for your kids.

Cut the lower edges of eight bags to make them opened from up and down edges. Leave two opened from the top only.

keep the straps those have been cut from the lower edges as we'll use them later.

Tie those straps together to make a tail for the balloon.

Use tape to connect two plastic bags together. Continue this process until you finish all the bags.

Add the tail to the balloon.

Tie a long thread to the balloon.

Make a small opening into the last bag and use an air bump to blow the air into the balloon.

Try it in an open area on a sunny day.
