It is very easy to make a cloud inside a bottle. There are many ways to do it but I would do the basic way of doing it. This works when the water inside the bottle evaporates, because of the smoke of the matchstick which makes it evaporates.
Step 1: Gather Your Materials
First, you need to gather your materials. You will need a soda bottle, matchbox with the matchstick, and 25 ml cup of water.
Step 2: Get a Soda Bottle and 25 ML Cup of Water
First get a soda bottle also the 25 ml cup of water. The bottle must be dry and clean. Pour the cup of water inside the bottle. Close the cap. Shake the bottle to spread the water
Step 3: Changing the Temperature
Remove the cap. Light the matchstick by rubbing it on the rough part of the box. You can either drop the matchstick in the bottle or get a sports bottle cap and suck in the smoke inside.
Step 4: Making the Clouds
Press the bottle hard to apply pressure. Then release it and do this step as many times as you can to make the clouds inside. Finally remove the cap and push the bottle so the cloud would go out, and there you have it a cloud in a bottle.
