MESSY SCIENCE EXPERIMENTS
My book, Chemical Reactions!: With 25 Science Projects for Kids, is out! To celebrate, I’m sharing two messy science experiments from the book. Okay, in the interest of not making too much of a mess, one chemistry science experiment is high on the messy scale, and one is more contained. Both are chemistry experiments using food coloring. I love color, as you can probably tell from my website design.
Wig or not, these easy stem experiments are fun, colorful, and use materials you most likely have in your junk drawer or under the sink.
We are Macgyver-ing it! (My spell check hated that not-a-word.) But you’ll like that you use materials from the supply closet! It makes the science more approachable. Plus, using everyday items puts the STEM concepts together for kids, as opposed to packets of powders in a kit.
Without further ado, let’s get messy! DIY chemistry science experiments with food coloring!
Easy stem experiments…
CHEMISTRY SCIENCE EXPERIMENT # 1 : MAKE A RAINBOW
SUPPLIES FOR MESSY SCIENCE EXPERIMENT # 1
2% Milk, Whole Milk, Half & Half, or Cream will work, but fat content makes a difference, which I'll explain below.
As promised, a science experiment with food coloring!
STEPS FOR MESSY SCIENCE EXPERIMENT AT HOME # 1 aka Make A Rainbow
All right, you’re saying sure, we see milk and soap and food coloring.
This is an easy stem science experiment, but where’s the STEM? (science, technology, engineering, or math?)
THE SCIENCE BEHIND THIS LESS MESSY CHEMISTRY EXPERIMENT
WHY IS THIS A CHEMICAL REACTION, ANYWAY?
A DASH OF SCIENTIFIC METHOD
Oh, oh! Now we’re using scientific method because we’re asking a question and forming a hypothesis w/ our why.
Time for messy science experiment # 2. This one is rather messy …and fun!
CHEMISTRY SCIENCE EXPERIMENT # 2 : MEGA FOAM
SUPPLIES FOR MESSY SCIENCE EXPERIMENT #2
2 LITER CLEAN PLASTIC BOTTLE
16 ounce works too, but it's messier...uh, more fun with a bigger bottle
HYDROGEN PEROXIDE (3% is fine)
1 cup for the 2 liter bottle / 1/2 cup for the 16 ounce bottle
LIQUID DISH SOAP
A tablespoon or so.
4 PACKETS OF DRY YEAST
Or 2 packets for a 16 ounce bottle
~3-5 TABLESPOONS WARM WATER
SMALL BOWL OR CUP
To mix the yeast & warm water

VIDEO OF MESSY SCIENCE EXPERIMENT # 2
Below is my first –and quite possibly last– attempt w/ TikTok to create a compilation of a chemistry science experiment. I started w/ a 45 second video and a few stills. Four hours later, here’s the result! HA!
It felt like four hours.
THE SCIENCE BEHIND THE MESSY SCIENCE EXPERIMENT
ANOTHER DASH OF SCIENTIFIC METHOD
I admit that I was tempted to order 6% H2O2 for a more showy video, but that seemed counter to the theme of this post.
EASY STEM EXPERIMENTS : YEAST!
Because I can’t resist, I have to chat a little bit about amazing yeast!
Yeast is alive. It is a single-celled microorganism and technically a fungus.
Yeast is a beast!
MESSY SCIENCE EXPERIMENTS
Safe chemistry science experiments such as these illustrate how chemical reactions occur. By using household items, these messy science experiments at home will enhance kids’ understanding of the chemistry they encounter every day. And they’re pretty because they’re science experiments with food coloring!
Which experiment will you try first?
