Take the help of dry sponge, marshmallows cut in half, clay, foam, chewing gum or hot glue to connect the wheels to the axles. Your balloon car will drive crooked if the axles (skewers) are not facing perfectly forward. To make the balloon car drive straight, the straws holding the skewers must be parallel to one another and totally perpendicular to the water bottle.
Step 12: Changing the Appearance
Want to turn one of these experiments into an awesome science fair project? To help students work through this process, be sure to build in planned “stops” at each step for students to record their thoughts and progress as they work through product iteration cycles. First, designers Define the challenge they are facing, then Learn more about the problem and Explore existing solutions.
Build a Balloon-Powered Car
To bring our idea of building balloon powered car in to reality, just grab the supplies listed here and get ready. This balloon car design contains one of 6 Simple Machines, the wheel and axle. Simple machines can help make difficult tasks easier. They change the force needed to complete the difficult task.
Step One – Making the wheels & axels

A small amount of friction is necessary for propulsion. Making the surface of the wheels a little less smooth, increases the resistive forces and eases the movement on a surface. Fastest cars with high momentum have their balloon straws parallel to the plane on which they race. Another style of balloon cars, for this one, first use your imagination to construct LEGO cars in various designs. Then, put a few blocks at the back of your cars to hold the balloon straw ensemble. Making a wide lightweight car makes the structure more stable and prevents it from falling over.
This little car is made from recycled materials and is propelled by a balloon. The principle behind the movement in this car is the same one used in real rockets and jets that shoot a high-speed stream of gases out the back of their engines, propelling the vehicle forward. In this project you will use this principle to build a toy car that is propelled forward by the stream of air escaping a balloon through straws as it deflates.
The University of Texas in Austin this afternoon, we saw protesters physically clashing with police. And so when you have a question that feels as urgent as this war does for a lot of people, I think it reverberates in an incredibly intense way on those campuses. And there’s something like — I don’t know if it’s quite a contradiction of terms, but there’s a collision of different values at stake. So universities thrive on the ability of students to follow their minds and their voices where they go, to maybe even experiment a little bit and find those things. But college campuses, at least in their most idealized form, are something special.
Place another wedge shape on the workplane and size it to 20mm wide, 10mm long and 15mm tall. Change the wedge to a hole, and rotate it to match the image. Select the cylinder and press the left arrow key on the keyboard 5 times. This will move the hole 5mm to the left away from the end of the box. Place a cylinder on the workplane and size it to 11mm in diameter and 25mm tall. Place a box on the workplane and size it to be 20mm wide, 60mm long, and 20mm tall.

Glue the bottle top on the roof and the straws at the back in place, making sure that they are all secure and that there are no holes for air to escape from. Tape the end of the straws together and gently push the straws through the hole in the roof and out of the small hole you cut at the back of the car. Make two small holes with the tip of the glue gun into the bottle top for the two straws to fit snugly into. On one end of the “window, bonnet, grill and roof” piece, cut a small hole, large enough for the two straws to fit through.
Now it’s time to give your car an engine so it can move! The balloon is what will provide the force to make your car race. Cut 2 straws for the axles (7cm long) and glue then onto the lines on the under carriage of the car. Cars carry and deliver objects such as foam blocks or action figures to a designated target area in a specified amount of time. Cars that carry basic objects have met the challenge while those that carry more complex objects or get there faster earn extra recognition. A good design cycle builds in time for the designer to Reflect on their product and the process of making it, looking for learning habits and insights that will help in future challenges.
Place a piece of Blu-tack underneath the centre of the bottle top lid. Many bottle top lids already have a dimple to show the centre. If yours doesn’t you will need to measure to locate this. Make sure nothing is selected, then click Fillet.
When you release the balloon, this stored potential energy is converted to kinetic energy, the energy of motion. Eventually, the car will come to a stop, but the energy is not lost—it is converted to other forms like sound and heat (from friction). Decide on the best design of balloon race cars by trying on wheels of diverse sizes since that influences how far the car can go. You can also trim the exhaust straw to various lengths or use straws having different diameters to check which system supplies maximum thrust. This lesson gives students an opportunity to learn about common hardware items as well as technical design and construction techniques.
