Why was the skewer able to go through the balloon without it popping?
Balloons contain elastic polymers that allow the balloon to stretch. Placing the dish soap on the skewer reduces enough surface tension on the balloon to allow the skewer to puncture the less-taut ends of the balloon. The polymer chains close around the skewer, preventing the balloon from popping.
Why did you add a lubricant to the skewer before inserting it in the balloon?
Adding a little bit of a lubricant, like soap or oil, to the skewer before pushing it through the balloon makes it easier to get the skewer through the balloon and makes it less likely to pop.
What happens when an inflated balloon is pricked with a pin?
When an inflated air balloon is pricked with a pin the balloon will burst. The property of the gaseous state exhibited by this observation is diffusion.
How do you get a stick to stick to a balloon?
Items Needed for Experiment
- Step 1: Blow up the balloon and tie off the opening.
- Step 2: Take the sharp thin stick and push it through the top end of the balloon.
- Step 3: Keep pushing the balloon until it exits from the bottom of the balloon, near the tied off opening.
What is the hypothesis for baking soda and vinegar?
Our null hypothesis is that if different amounts of baking soda react with 70mL of vinegar, then the mean volume of bubbles formed should be the same because the amount of baking soda used does not affect the amount of carbon dioxide produced.
Why does a balloon explode?
A balloon pops when the material that makes up its surface tears or shreds, creating a hole. Normally, there is a balance of the balloon skin’s elastic tension in which every point on the balloon’s surface is being pulled by the material surrounding it.
What happens when an inflated balloon is pierced and released?
Newton’s third law explains how balloons and rocket engines work. When the neck of an inflated balloon is released, the stretched rubber material pushes against the air in the balloon. The air rushes out of the neck of the balloon.
What causes a balloon to stick?
Possible factors in the balloon sticking are: Wool, clothes, and other things to rub against the balloon Materials to stick against (usually parts of the room) (Note that static electricity experiments work the best on dry days. If it is rainy or damp outside, it is possible that things will not work very well.)
What happens when you rub a balloon with static?
Rubbing the balloon with a piece of fabric gives it a negative charge, also known as static electricity. Enough static electricity will force the balloon to stick to neutrally charged surfaces, such as walls, by attracting the positive charge to the surface.
How do you get a balloon to stick to the wall?
Rub a balloon several times across the wool sweater or rug. Place it against the wall. Does it stick to the wall? Rub the balloon across the sweater or rug again. Bring it close to a friend’s hair. Does her hear leap up and stick to the balloon?
Do you ever see balloons stick to things?
Have you ever seen a balloon magically stick to something? Getting balloons to stick to objects through static electricity is classic trick, but it never ceases to amazing young children. You might have seen someone get balloons to stick to hair, giving the person a head full of static.
