20 Balloon Experiments to Make Your Lessons Really Pop
- Blow up a balloon… without blowing.
- Design a balloon-powered car.
- Skewer a balloon without popping it.
- Float a balloon-powered boat.
- Create ice crystal explosions.
- Explore the science of swim bladders.
- Assemble a heart pump model.
- Learn how lungs work.
Do water balloons sink or float?
Warm water is less dense than cold water, so the cold water in the water balloon was more dense than the hot water and so sank. As the water cooled down, it’s density increased making the balloon float again.
What happens when you put a balloon in tap water?
What’s happening: The water is made of positive and negative charged particles. When you bring the balloon towards the water, the positive charged particles in the water will move the water towards the negatively charged balloon since positive and negative charges are attracted to each other.
How do you skewer a balloon without popping it?
Dip the tip of a skewer in Vaseline and spread the Vaseline along the entire length of the skewer. If you are careful, you should be able to push the skewer all the way through the balloon without popping it. Insert the skewer with a gentle twisting motion into the end of the balloon opposite the knot.
How do you make a balloon rocket?
What to do
- Tie one end of the string to a chair, door knob, or other support.
- Put the other end of the string through the straw.
- Pull the string tight and tie it to another support in the room.
- Blow up the balloon (but don’t tie it.)
- Let go and watch the rocket fly!
How do you make a balloon experiment?
Instructions
- Using a funnel, pour about a third of a cup of vinegar into the bottle.
- Then insert another funnel into the mouth of the balloon.
- Place two teaspoons of baking soda into the funnel so it falls into the balloon.
- Next, secure the the mouth of the balloon over the top of the bottle.
Do balloons float in a pool?
The balloons will have different buoyancy, as a result of the different amounts of air and water in each one, which will cause them to float at different depths in the pool.
Will hot water pop a balloon?
When the balloon is filled with water, the water absorbs the heat. Because there is no weak point, the balloon doesn’t pop.
What is the science behind hot air ballons?
Hot air balloons are based on a very basic scientific principle: warmer air rises in cooler air . Essentially, hot air is lighter than cool air, because it has less mass per unit of volume. A cubic foot of air weighs roughly 28 grams (about an ounce). If you heat that air by 100 degrees F, it weighs about 7 grams less.
What is the science behind self-inflating balloons?
Self-Inflating Balloons contain two chemicals that are kept from reacting until the balloon is activated by hitting it. One of these chemicals is baking soda. In some cases the baking soda is mixed with a binder to form a small pellet. The other chemical is citric acid that is dissolved in water and stored in its own plastic bag.
What is the balloon rocket experiment?
The balloon rocket can be used easily to demonstrate simple physics, namely Newton’s third law of motion. A common experiment with a balloon rocket consists in adding other objects such as a string or fishing line, a drinking straw and adhesive tape to the balloon itself.
