Rain In A Jar
First we are going to need a few things to make our rainstorm happen. These will only be a small collection of things that can be found around the house. This experiment requires an adult for some of the tricky work, but it's a fun one for kids too. This is fun for all ages, so let the kid in you shine.
What We Need
- Glass Jar with a Metal Lid.
- Butter Knife
- Pot Holder
- Around 1 Cup Of Water
- A Hammer
- A Nail
- A Few Ice Cubes
How To Make Our Rainstorm
- With the hammer and the nail, make 5 or 6 random dimples on the inside of the metal lid. Make sure you don't poke any holes through the lid. You only want to make bumps.
- Put the jar on top of the towel. The towel is just to protect any surface from excess water, so you may or may not need it.
- Put the butter knife in the jar. You do this to conduct heat away from the glass jar so it won't break when you put the hot water in.
- Bring the cup of water to a boil in the saucepan.
- Carefully pour the hot water into the jar.
- Now use the pot holder to take the knife out of the jar. Be careful. The knife is hot.
- Place the metal lid upside down on top of the jar. Make sure the jar is completely covered by the lid.
- Place the ice cubes on the lid, as many as will fit.
- Pour a little bit of cold water onto the ice.
- Sprinkle a pinch or two of salt on top of the ice. These last two will help the ice melt a little bit while making it even colder.
A rainstorm happens when a mass of cold air comes into contact with a mass of warm air. Moisture from the warm air is pushed up to form clouds. As the moisture gets too heavy, it falls back down in the form of rain.
