A balloon experiments is with a balloon is an application of Newton’s laws of motion. Blow a balloon without using your mouth experiment will help to learn chemical reactions by acids and bases. Through designing a balloon-powered vehicle, one can explore Newton’s laws of motion. Also, can learn the significance of using recyclable items. Spear a Balloon without Popping it experiment gives information about polymers and how to stay relaxed in stressful situations.
Step-by-step Instructions to Perform the Balloon Experiment
Balloon Rocket Experiment
Aim: The application of Newton’s second and the third law of motion.
- Few Balloons
- Inflation Pump
- Kite string
- Adhesive tape
- Cut the straw into two-halves. Pass one end of a kite string via one half.
- Bind one end of a string to a chair or door or window or something heavy and another end to a distant object at some height horizontally. Make sure that the string is tied firmly.
- Now, blow the balloon. Hold the balloon with fingers to prevent the release of air.
- Fix balloon with straw using adhesive tape.
- Now, release the balloon, and it will run like a rocket.
Blow up a Balloon Without Using Your Mouth
Aim: How a chemical reaction occurs between acids and bases.
- A Tiny Soda B
- Baking Soda
- Vinegar or apple cider vinegar
- Pour 1/3rd of vinegar solution into the soda bottle with the help of a funnel.
- Wash the funnel properly and put two teaspoons of baking soda into the funnel so that it falls into the balloon
- Secure the mouth of a balloon over the top of a soda bottle.
- Now, let the baking soda fall into the bottle.
- Observe that the reaction. The reaction between baking soda and vinegar gives foam. This foam inflates the balloon.
Designing a Balloon Powered Vehicle
Aim: How to build a balloon-powered car and use air pressure to run it on the floor.
- Pair of scissors
- Rigid cardboard/foam core
- Four bottle caps
- Use a ruler and measure two 7 cm pieces on a straw. Cut the straw into two halves.
- Cut the cardboard with a measurement of \(6.5 cm \times 17 cm\). Stick the two straws to the underside of the base with tape. These straws will hold the axles. Arrange the straws parallel to each other to lie perpendicular to the centerline of the cardboard base.
- Cut the ring end of the balloon.
- Flip the cardboard and slide the straw into the balloon with tape to make an airtight connection
- Make a hole in a bottle cap. Cut the sharp ends of two skewers. These skewers work as an axle. Slide these into the central holes of caps.
- Turn the cardboard again. Attach two pairs of wheels. Make sure that they are perfectly parallel to each other.
- Blow air through the pipe. The balloon will inflate and the car start moving.
Spear a Balloon Without Popping It
Aim: How we can pierce a balloon without popping it.
- Inflate a balloon approximately to full size. Keep 1/3rd of air out and tie a knot in its open end. Look all over the balloon and find a thick area. Mark the place and pierce the balloon with a wooden skewer.
- Coat the skewer with a lubricant like vegetable oil or dish soap.
- Push the sharpened end of a skewer to the thick area of the balloon and slide it till it reaches its opposite end.
- Gently, remove the skewer. Hence, the air will leak, but the balloon won’t crack.
FAQs on Balloon Experiments
Question 1: What is the importance of balloon experiments?
Answer: Some significant points of balloon experiments are:
- Balloon experiments are well-liked among school students. Many experiments are possible because balloons are used in extensive student hands-on science projects
- Balloon experiments work as a simulator to study the working of real-life objects.
Question 2: Why a balloon expands in hot water?
Answer: The temperature of a balloon increases in hot water. As the air molecules make a Brownian motion, these molecules start moving fast and collide with each other and result in increased energy. This increased pressure makes the balloon expand.
