Toilet Paper
Air Pressure Experiment!
We have a look at a quick and easy experiment using air pressure to hold water in a bottle using only toilet paper!
Following the instructions below, you create a circumstance where the air pressure outside of the bottle will match the weight of the water, for at least a few moments before the toilet paper is too wet to hold anything. It's a fun way to see air pressure in action!
Materials
• A small bottle with a smooth rim at the top
• Toilet Paper
• Bowl
• Water
Procedure
1. Fill your water bottle all the way to the brim.
2. Lower the square of toilet paper down over the bottle top, letting it make contact with the bottle and the water.
3. Over the bowl, flip the bottle and toilet paper upside down. It won’t take long for the water to soak through the paper but you have a moment to see the effects of air pressure holding everything in place!
This experiment is great for beginners and can be done with household ingredients.
