    Creating clouds in a bottle

Creating clouds in a bottle

cloud in a bottle

Have you ever tried to make your own weather phenomena? We aren't talking about a rain dance or praying for snow, but simply creating a cloud in a bottle.

Creating your own cloud is very simple. All you need is a two litre plastic bottle, some warm water and a couple of matches... and adult supervision if you are too young to use matches.

Pour a small amount of warm water into the bottom of the plastic bottle, leaving the cap off. Then light a match and blow it out. As soon as you have blown it out, you need to drop the match into the bottle and quickly tighten the water bottle cap back on.

With the lid on, gently squeeze the bottle a couple of times. Did you see a little and very brief puff of whiteness when you released the pressure? That's the cloud you've made. If you exert more pressure to the bottle, a more noticeable whiteness should appear.

But how does the cloud form in the bottle?

By squeezing the bottle you exert pressure. This causes the temperature inside the bottle to increase. When you release the pressure, the temperature in the bottle decreases causing water molecules to condense.

The smoke particles from the match enable the water molecules to condense and stick together around the smoke creating the cloud in a bottle.

Have a go for yourself, but don't blink or you'll miss it!
