If you hold a fire up to a balloon, it pops instantly. What if you could prevent this from happening? In this project, we do just that.

Make your own greenhouse - out of a balloon! Your child will learn how greenhouses work as they plant radish seeds and watch them grow.

Design and build a balloon rocket from an existing design. Think of the ways in which existing designs can be improved, new practical applications

In this challenge, students are tasked with creating a car that can be powered by a balloon!

Science fair project which uses a camera to observe the surface of a balloon in the moment of its explosion.

Kids conduct a cool balloon rocket experiment in this fun science fair project idea. Does a greater volume of air mean a greater distance traveled?

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

In this exciting design challenge, your child will use design thinking skills to create a mixture that can inflate a balloon.

The objective this science fair project is to determine whether a bigger bag will allow a homemade hot air balloon to fly higher than smaller bag.

Check out this fun science fair project to make a vinegar and baking soda balloon and demonstrate how gas is created as a result of the chemical reaction.

In this science fair project, kids start a chemical reaction that will make a balloon inflate itself!

How powerful is the reaction between baking soda and vinegar? Find out here!

Kids will learn how to make a steam powered rocket boat, also called a putt putt boat or a pop pop boat, in this great science fair project for 4th graders.

When you rub a balloon on your head, your hair stands up; but is that true for everyone? Does hair color affect static electricity?

In this fun science experiment, make a balloon car and test it on different surfaces to learn about sliding friction and rolling friction.

The objective of this science fair project is to examine the basic principles of air pressure using simple materials like a balloon, straw and string.

Learn whether Mylar Balloons last longer than Latex Balloons or vice versa.

This project examines how temperature affects the volume of gas in balloons.

This cool science fair project teaches kids about temperature, density and buoyancy using balloons that float with normal air. No helium required!

This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

This project examines Newton's First and Second Laws of Motion with a bicycle and water balloons.

This science fair project idea examines whether adding gelatin causes a solid to have a higher melting point and/or melt slower.

Check out this fun science fair project idea for middle school students to learn about the effects of temperature on the density of a gas such as air.

This science fair project idea compares the mass and density of objects.

In this experiment you will become familiar with the properties of dry ice while creating interesting effects like ice bubbles!

In this CD hovercraft science project, students will construct their own DIY hovercraft.

This science fair project idea provides evidence that air is everywhere and takes up space.

Can the force of air be used to propel a vehicle? This science experiment provides step-by-step instructions to help you answer this question.

Determine which material produces the strongest static charge.

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.
