Alpha science classroom:DIY Balloon Skewer

Children learn that some objects cannot be mixed together, just like balloons are afraid of sharp objects. But this impossible task can be easily accomplished by children with the help of science. Today, Alpha Science Classroom teaches children to DIY balloon Skewer, showing the magical and magical effects of children's physical science experiment projects, unlocking the knowledge of polymers for children, and experiencing the fun that comes from kid's science experiment activities.

Alpha Science Classroom: DIY balloon Skewers experiment materials

  • Several latex balloons (9-inch size works well)

  • Bamboo cooking skewers (about 10 inches long)

  • Cooking oil or detergent

  • Sharpie pens

  • Fountain pens

Alpha Science Classroom:steps to experiment with DIY balloon skewers

Step one. First, children inflate the balloon until it is near full size, then release about one-third of the air. Tie a knot at the end of the balloon.

Step 2: Children need to examine the balloon carefully. You will find thick areas of rubber at both ends (where the knot is tied and at the other end). Here you will pierce the balloon with a skewer, but not yet. Continue reading.

Step 3: The kids will need to put a few drops of vegetable oil or detergent on the wooden skewer (be careful not to accidentally get splinters out). As you may have guessed, any liquid works well as a lubricant.

Step 4: The children place the tines of the fork on the thick end of the balloon and push the fork into the balloon. Be careful not to stab yourself or the balloon with the fork. Just use light pressure (and maybe a little twisting action) to pierce the balloon.

Step 5: Children push the fork through the balloon until the tip of the fork touches the other end of the balloon, where you will find the other thick part of the balloon. Continue pushing until the fork penetrates the rubber.

Step 6: The children gently remove the kebab from the balloon. Of course, air will leak out of the balloon, but the balloon will not burst.

Part 7: Let's do it again, but this time you will see the "pressure" hidden in the balloon.

Before the kids blow up the balloon, use a sharp needle to draw about 7-10 dots on the balloon. These dots should be about the size of a dime. Be sure to draw them on the ends of the balloon and in the middle.

Step 8: Inflate the balloon to half full and snap the ends. Observe the different-sized dots on the balloon.

Looking at the size of the dots, where on the balloon are the latex molecules stretched the most? Where is it stretched the least?

Step 9: Children put a few drops of oil or detergent on the skewer to help get it through the balloon.

Step 10: Children use their previous observations of the points on the balloon to determine the best place to pierce the balloon with a fork. The goal, of course, is not to blow up the balloon!

Alpha Science Classroom: DIY Balloon Skewer, Science Principles

Alpha Science Classroom tells kids that the secret to this fun children's physical science experiment is when using rubber molecules in the part of the balloon subjected to the least amount of stress or strain. If you can look under a microscope at the rubber that makes up the balloon, you will see many long chains or molecular chains. These long-chain molecules are called polymers, and the elasticity of these polymer chains causes the rubber to stretch. Blowing the balloon stretches these polymer chains.

After drawing on the balloon with a Sharpie, you may notice that the dots at the ends of the balloon are relatively small compared to the enlarged dots in the middle of the balloon. You have just discovered the area of least pressure - the end of the balloon. You have wisely chosen to puncture the balloon at the point where the polymer molecules stretch the least. The long molecular chains stretch around the stick to prevent the air in the balloon from rushing out. When you remove the kebab, you feel the air leak out through the holes pushed through the polymer chains. Eventually, the balloon deflates, but it never bursts, right?

Unless you have the help of a piece of clear tape, trying to puncture the middle part of the balloon is nearly impossible. Under normal circumstances, the long chains of rubber molecules are under a lot of pressure or tension and can easily tear with a slight puncture. The clear tape helps hold the rubber molecules in place and prevents the balloon from tearing when punctured. To fool those who know how to put a bamboo skewer through the end of the balloon, the magician will secretly place scotch tape in the middle of the balloon to prevent the balloon from entering this "forbidden zone". That's just another way the smartest people say it." How do you do it?"

In addition to helping children learn polymer science, this kid's science experiment can also be used as a life lesson with a string of balloons showing how to handle a potentially stressful situation. The key to handling any stressful situation is to find the least stressful place and use that as an entry point to work on easing the tension. In other words, every stressful situation has a "best entry point". If you want to successfully dissipate potential turmoil, you need a good exit strategy. At any age, this is a great physical science lab course for kids!

Boom! The kids' DIY balloon Skewer is a success, so go show your friends the magic! Today, Alpha Science Classroom's physical science experiments for kids are over. We hope that children will learn about the physical science knowledge contained in polymers through this fun kid's science experiment activity, learn in a happy atmosphere, develop their various abilities and grow up to be future scientists.

Alpha Science Toys also prepared many interesting children's physical science experiment kits for children to show various interesting physical phenomena to help children become happy scientists and achieve their scientific dreams!
