It's almost the Fourth of July - one of the Prez's and I's favorite holidays!
Why you ask?
The answer is simple; we love the fireworks!!!
And today, we are going to share how you can make your very own fireworks and explode them right in your kitchen!!
Before we get started, let's watch this video to learn a bit more about the science behind fireworks.
Wasn't that fascinating?
Now, that we understand what is going on in the sky. Let's recreate it in the kitchen!!
Ok, so by now you have figured out that we are not making the exploding with fire kind of fireworks in your kitchen. It kinda falls under the same rules as when we showed you how to make a rocket at home.
We are making the oil and water kind - not exactly the same, but still super cool!
Let's get started!
Step 1. Pour a bit of oil in a bowl and add a few drops of food coloring.
Step 2. Break the drops into tiny droplets with a fork.
Step 3. Slowly add the oil mixture in a jar filled partway with water.
Step 4. Wait a moment and observe your fireworks!
Oil and water don't mix. This is because one (oil) is nonpolar and the other (water) is polar and because molecules like to hang out with other molecules that are just like them. They are kinda exclusive like that.
Anywhoo, it turns out that food coloring is also polar, so it doesn't want to mix with the oil. When gravity takes effect, the food coloring droplets turn tail and head for the hills, a.k.a., the water.
Wasn't that fantastic?
And the best part about it is that you can do it over and over again without waking up the sleeping baby!
We’d love to see the fireworks you create – post a pic on Instagram and tag it with @sassafrassci and the Prez and I will check it out!

So, our astronomy leg is currently in production, but as you know we have already experienced it. Let's just say - it was a blast! And without spoiling the adventure, we wanted to bring one of our local experts from our astronomical adventure to share a bit about our solar system with you all.
