solar balloon!

The freshmen got a chance to experience a solar balloon, a solar balloon is a like huge black trash bag that when gets laid out onto concrete and filled up with air from a fan and heat from the sun. The bag begins to rise and as soon as you tie the mouth of the bag it floats up high. their is a person on the other side of the bag holding a string so the bag doesn't fly away. the bag is approximately 50ft long but it had a hole in it so it was 40ft. So the freshmen had a wonderful time chasing the big solar balloon- Sarah Swank:)
