Steam Vacuum Experiment
Edited by David Collins, Eng, Doug Collins
In today's project we will show you how to do make a steam vacuum.
Materials. The materials you will need for this project are:
- Oven mitts.
- A deep dish glass container.
- Glass bottle.
- Some ice cubes.
Fill your glass container up with some cold water.
Now, fill your glass bottle with water about 4 cm from the bottom.
You need to make sure that your glass bottle can be tipped over on its side without water pouring out of it.
Once your bottle is partially filled, go ahead and put some ice in your glass container. We need the water to be cold.
Take your bottle filled with the small amount of water and place it in your microwave on full power for 1 minute and 40 seconds.
Using your oven mitts, remove your bottle from the microwave then quickly flip the bottle upside down pouring out the excess water inside.
Submerge your bottle underwater applying pressure to the bottom. You should feel a rapid force of water rush inside the bottle replacing the space left by the condensing steam.
This experiment works best when you pull your bottle straight out of the microwave then place it directly in your cold water container. The longer you hesitate, the harder it is to get the best results.
If you are wondering why we added ice cubes to cool down our water in the container, it's because we want the steam inside the bottle to cool down and condense at the fastest rate. Since the steam takes up a larger volume of space when it's hot, there is a vacuum created inside the glass bottle once the steam condenses into a denser gas form (when it starts to cool down). This experiment could be done with larger bottles, which would yield a larger vacuum suction force. If you have any questions, feel free to leave them in the section below!
