15 Awesome Balloon Science Experiments
When two different-sized bottles are used, the smaller one would have only expanded the balloon slightly; the larger bottle would have expanded it more. Then insert another funnel into the mouth of the balloon. You will start with a full-length dress-sized dry-cleaning bag. Take it with you wherever you go. The first hot air balloon was invented in by two brothers, Joseph and Etienne Mongolfier. As mentioned before, letting the yeast dissolve in water makes it active.

Research Question When making your own hot air balloon, does a bigger bag cause the balloon to fly higher than a smaller bag? The fundamental principle behind the flying hot air balloon is density. Make the experiment even more interactive and have your kids try to race the balloon across the room! Mechanical Engineer Mechanical engineers are part of your everyday life, designing the spoon you used to eat your breakfast, your breakfast's packaging, the flip-top cap on your toothpaste tube, the zipper on your jacket, the car, bike, or bus you took to school, the chair you sat in, the door handle you grasped and the hinges it opened on, and the ballpoint pen you used to take your test.

Description: No problem, save it as a course and come back to it later. My kids really enjoyed this simple experiment and had fun doing it over and over with balloons of different shapes and sizes. You need to hold properly the bottle when you mix the baking soda into vinegar. Instead of the burner, you can join two opposite points on the circumference of the base ring by a drywall tape strand and place a candle over it to fuel the hot air balloon.
