Since I Put the Bottle
Can science accident upwards a balloon?
In this piece of cake science experiment, kids can explore how matter behaves when heated and cooled. Watch our demonstration video, gather your materials, print out your instruction sail to get started. Then, hash out your findings with our like shooting fish in a barrel to understand caption of how it works beneath.

Supplies Needed
- 8-inch Balloon
- Empty ii-Liter Bottle
- 2 pans (I used 9-inch square pans)
- Enough Ice & Cold Water to Fill i Pan
- Enough Hot Boiling H2o to Fill up another Pan
Employ a Canteen to Blow-upward a Balloon Science Experiment Instructions
Footstep 1 – Beginning with an empty two-liter bottle and secure a balloon around the oral cavity of the bottle. Helpful Tip: 8-inch balloons work best for this experiment. When nosotros tried this with a 10-inch balloon, information technology didn't inflate entirely.
Step 2 – Prepare two pans of h2o. Fill up ane pan with water ice and cold h2o. Fill the other pan with hot boiling water. What practise you think will happen if you place the bottle in the pan with the hot water? What do you think will happen if you identify the canteen in the pan with the common cold water? Write downward your hypothesis (prediction) and so follow the steps below.
Footstep 3 – Place the bottle in the pan with the hot h2o. Hold information technology in the pan for 30-40 seconds. Sentry what happens to the airship and brand some observations. Does the balloon inflate? What do you remember will happen if you remove the canteen from the pan with the hot water?
Step four – Remove the canteen from the hot h2o and place information technology on the table for a few seconds. Discover that the balloon stays inflated. What practice you think volition happen if you lot put the bottle in the pan with the cold water? Is this dissimilar than your offset prediction?
Footstep v – Place the canteen in the pan with the common cold water. Hold information technology in the pan for 30-twoscore seconds. Watch what happens to the balloon and brand some observations. Does the balloon deflate? What practise you call up will happen if you remove the canteen from the pan with the common cold h2o?
Step 6 – Remove the bottle from the cold water and place it on the table. The balloon will remain deflated.
Do you know the why the airship inflated and deflated throughout the experiment? Find out the answer in the how does this experiment work section below.

How Does the Science Experiment Work
Fifty-fifty though the bottle looks empty, information technology is actually filled with air. Past placing the balloon on top of the canteen, you lot trap the air within of the bottle. This experiment is a not bad style to bear witness how matter behaves when it is heated and cooled. Matter expands (gets bigger) when heated and contracts (gets smaller) when cooled.
When the bottle is placed into the pan of hot water, the heat from the water causes the air inside the canteen to estrus up. Equally the air in the bottle heats up, the molecules of the air begin to move faster and take up more infinite. The air from the bottle then moves into the airship causing information technology to inflate.
When the bottle is removed from the hot h2o, the balloon will stay inflated. This is because the air molecules in the canteen are still hot. If you lot leave the bottle out of the water for a while, information technology will somewhen absurd downward. When the air in the bottle cools downwardly, the molecules of air dull down, move closer together, and take upwardly less space. This will cause the airship to deflate.
When the bottle is placed into the pan of ice-cold water, the cold water causes the air within the bottle to cool down. As the air in the bottle cools down, the molecules of the air boring down and have up less space because they move closer together. The air then moves out of the balloon and back into the bottle, causing the airship to deflate.

- Stab a Straw through a Potato – Yep, it really is possible and it's all because of Air Pressure
- Upside down Water Drinking glass – Plough a glass total of water upside down…without spilling a drib!
- Go along Towel Dry Nether Water – Use unproblematic science to keep the newspaper towel dry afterward submerging information technology in water
I promise you enjoyed the experiment. Hither are some printable instructions:
Materials
- 8 inch Balloon
- Empty 2 Liter Bottle
- 2 pans (I used 9inch square pans)
- Enough Ice & Common cold Water to Fill one Pan
- Plenty Hot Boiling Water to Fill another Pan
Instructions
- Showtime with an empty two liter canteen and secure a balloon effectually the oral cavity of the bottle. Helpful Tip: 8inch balloons work best for this experiment. When nosotros tried with a 10inch airship, it didn't inflate entirely.
- Prepare two pans of water. Make full 1 pan with water ice and cold water. Fill up the other pan with hot boiling water.
- Place the bottle in the pan with the hot h2o. Hold information technology in the pan for 30-40 seconds and scout the balloon inflate.
- Remove the bottle from the hot water and place on the tabular array for a few seconds. Find that the balloon stays inflated.
- Identify the bottle in the pan with the cold water. Hold it in the pan for 30-forty seconds and water the balloon deflate.
- Remove the bottle from the cold water and place on the table. The balloon will remain deflated.
