Sometimes I just want to mix up a dreary day with some fun, and these kitchen science experiments are some of my absolute favorite! These science experiments are tested from items that most households have commonly available. If you are missing an item, likely you can easily pick it up at a store near you and you want to. Check out some of my absolute all time favs below. Elephant toothpaste? Glowing eggs? Yeah, you need to see these kitchen science experiments stat! Even better I’ve included links to youtube videos so you can see the experiments in action!
7 Brilliant Kitchen Science Experiments That Are So Easy To Try
Elephant toothpaste is one of my all-time favorite chemistry experiments. I love the big wow it receives! This experiment is a chemical reaction that breaks down the Hydrogen Peroxide (also known as H2O2) into water and oxygen. When the oxygen is split by the reaction, it gets trapped inside the soap creating bubbles, lots of bubbles. Be careful as a byproduct of this reaction is heat, and the more advanced versions of this experiment can get very warm quickly!
Glowing Dissolving Eggshell
You may remember the classic experiment of dissolving an eggshell in vinegar from your childhood. You can try it on both a hardboiled egg or even on a raw egg. Take the experiment up a notch and try dissolving a highlighter into the vinegar before soaking the egg. This extra step definitely ups both the cool and gross factor in this experiment!
This fun experiment about density will also remind your kids why drinking lots of sugary soda is not the best idea. Your kids will have fun trying to figure out if different types of soda and beverages float or sink! In general diet sodas will float because they contain sugar substitutes and are simply not as heavy as full sugar sodas. Does that make diet soda better for you? Not necessarily, but it sure is a great way to bring up that conversation with your favorite kid!
Want to wow your kids? Try doing this walking water experiment that focuses on both absorption and color mixing. Set up your cups with absorbent paper towels and talk about how the water can defy gravity by slowly sticking to both itself and to the paper towel as it is absorbed up the paper towel. Once the liquids meet, the food coloring starts mixing for a very cool rainbow effect!
I have seen this super cool experiment everywhere lately, and you should totally try it with your kid! For older kids, it’s fun to hypothesize other variations for this experiment. Would other types of candy produce the same result with water? Would other liquids like milk, soda or juice produce the same fun rainbow result?
Color Changing Milk
This is another easy experiment that you do with items you already have in your kitchen. Use a little bit of soap to disrupt the surface tension of the milk and cause the fat in the milk to move. Once the milk starts moving, the food dye does too and it creates a really cool effect!
Get ready to get a bit messy, Oobleck is lots of fun. Oobleck is something called a non-Newtonian fluid. It is a suspension where the cornstarch particles are suspended in water. As you apply pressure, the cornstarch molecules compress and act more like a solid. If you release the compression, Oobleck will go back to acting like a liquid. Make sure if you add food coloring to your mix to add it to the water and stir well, or you will end up with your fingers bright blue or red! If you are playing in a space that you can get really messy, at the end play a game of hot potato with the ball of oobleck. Ohh it gets really fun when you don’t keep the pressure on the ball of Oobleck!!
