Rain in a Jar

Simple Science- BIG FUN!

Boy, oh boy, this week certainly has been all over the place when it comes to the weather! We've had sunshine, wind, rain and even freezing rain- I guess that's what you call a roller coaster of spring weather!

Let's explore the mysteries of the rain with this super simple DIY science experiment. All you need are a few items you probably already have around the house! Let the fun begin!

To get started you'll need
- Small clear jar filled about 3/4 of the way with water
- Shaving cream (gel shaving cream will not work)
- Food coloring
- small cups filled with 1-2 Tablespoons of water
- Pipette

1. Mix food a couple drops of food coloring into your small cups of water (represents rain)
2. Fill your clear jar 3/4 full with water (this represents the air)
3. Fill the top of the jar with shaving cream (this is your cloud)
4. Pipe a few drops of the food coloring mix onto the top of the "cloud"
5. Sit back and watch what is happening below the cloud

The colored water will slowly start to seep through the shaving cream cloud into the water below, just like rain! As the colored water (rain) saturates the cloud it eventually gets so heavy that it can no longer hold the water. It slowly rains into the jar/ air! 

We like to use a few different colors because as the rain comes down, the colors will start to mix and swirl! We like to observe how they move and mix together. 

We had a lot of fun repeating this experiment over and over again! It was a great accompaniment to the book Drop, which give an insightful look into the water cycle! Truly amazing! 

We hope you enjoy this very simple experiment! This is a fun way to enjoy the rain indoors with your rainy day dessert
