15 Science Experiments You Can Do With Your Kids

Time to get messy, light some stuff on fire, and use food products in ways they were never intended! Parents and teachers across the internet have found fun ways to teach kids science, and have documented the experiments for the rest of us. Here are 15 hands-on science lessons that will stick in a kid’s brain far longer than anything they get from a textbook.

1. Lemony Sudsy Eruptions @ Blog Me Mom


Fun Quotient: A much less stinky take on the trusty vinegar and baking soda eruptions. The experiment uses citric acid, food coloring, and clear hand soap to make fluffy frothy science.

Teaches: The baking soda base and the citric acid create an endothermic reaction while releasing carbon dioxide in bubble form. You have to look up endothermic reaction on your own. 

2. Alcohol soaked Money on Fire @ Barefoot in Suburbia

Fun Quotient: Holy crud—you’re burning money! Fire! Money! Fire!

Teaches: Combustion, or what a fire likes to eat. Rubbing alcohol, yum. Cold wet cottony dollar under the alcohol, meh. Not enough to keep burning once the alcohol is gone.

3. Homemade Rock Candy Skewers @ Home made simple

Fun Quotient: It makes pretty rocks you can eat!

Teaches:  Water evaporates, the sugar crystals don’t. The sugar precipitates, meaning it separates from the supersaturated sugar water. Seed crystals form on your stick, attracting more sugar crystals, until finally, about a week later, you got yourself some tasty science on a stick.

4. Make Your Own Electromagnet @ Science Bob


Fun Quotient: They get to use sharp things and electricity, which is Frankenstein-level cool. 

Teaches: Electromagnets are everywhere. They make motors spin, CDs play, and most modern cars run. This experiment shows the difference between a permanent magnet (the ones on your fridge) and the kind that can be turned on and off at will. When turned on, the electricity forces the molecules in the nail to attract metal, even though the nail itself isn’t magnetic. 

5. Invisible Ink From Lemons @ Show Tell Share


Fun Quotient: Invisible ink! Hello? INVISIBLE INK!! (Also fire if you want to go that route, but it’s not necessary or entirely safe to do so).

Teaches: Good old oxidation. Lemon juice is acidic enough to resist oxidation in open air, but a little heat “rusts” it right up.  

6. Walking on Eggs @ Steve Spangler Science


Fun Quotient: Like walking on hot coals, but somehow more naughty!

Teaches: Structure matters. No matter how flimsy an egg shell is, its actual shape gives it amazing strength, as long as you put the weight in the right place. 

7. Tea Bag Rocket @ Ordinary Life Magic

Fun Quotient: I really don’t think one can overemphasize how much children enjoy watching things burst into flame and fly around the kitchen. 

Teaches: Hot air rises, natch. But it also teaches “convection current,” which is the force that makes it shoot into the air.

8. Dancing Oobleck @ Housing a Forest


Fun Quotient: Oobleck is cornstarch and water, and if you didn’t play with it as a child then I am so sorry for you because you probably grew up in a Dickensian work house. By itself it’s fun, but add a sub-woofer and some paint, and you have a dance party. 

Teaches: Sound waves. You can’t see them, but they exist, and they like to party. 

9. Ivory Soap Monster @ bebe ala mode designs

Fun Quotient: Instead of having to wash with it, you get to nuke it until it becomes a frothy cloud of 99% pure mess.

Teaches: When the gas molecules trapped in the soft pliable soap get hot, they need more space. They make a break for it and take the soap with them. As the temperature of the gas increases so does its volume.

10.  Easy Marshmallow Catapult @ it’s always autumn


Fun Quotient: Weaponized Marshmallows.

Teaches: Force= Mass x Acceleration. A little thing going very fast will hit you just as hard as a big thing going slow. That’s Newton’s second law, don’t-cha-know. 

11. Magic Plastic Bag @ TinkerLab


Fun Quotient: Time to get stabby.

Teaches: How polymers work. Also, on a different level, why you’re not supposed to take the arrow out of a person after they get impaled in movies.

12. Gummy Bear Torture @ Science for Kids

Fun Quotient:  Deforming gummy bears with different evil potions, and the most gruesome of all: eating them.

Teaches: Osmosis, and which kinds of liquids do it best. 

13. Making an Optical Illusion @ Science-Sparks


Fun Quotient: It’s a teeny cartoon!

Teaches: Your eyes aren’t entirely reliable. Optical illusions occur because our brains fill in the gaps for whatever our eye isn’t processing. So two pictures become one.

14. Chain Reaction Popsicle Sticks @ Frugal Fun for Boys


Fun Quotient:  It’s tough to get started, but the payoff is clatter and splatter fun.

Teaches: Nuclear physics. Sorta. At least a demonstration of potential energy, kinetic energy, and chain reactions.

15. How to be a Polar Bear @ Discover and Learn

Fun Quotient: Goop is glory. 

Teaches: The natural glory of fat, and how arctic animals can survive temperatures that kill everything else.

Disney’s Steamboat Willie Has Been Immortalized in LEGO

Mickey Mouse recently turned 90 years old, and soon, you’ll be able to celebrate with LEGO. Steamboat Willie, the classic Disney short film that introduced Mickey Mouse to the world in 1928, has now been recreated in a LEGO set that will be released on April 1.

The 751-piece LEGO version of the S.S. Willie features grayscale bricks that recreate the original black-and-white aesthetic of the original film. The 10-inch-long LEGO boat features moving steam pipes and paddle wheels and comes with new Mickey and Minnie minifigures. It’s also equipped with a ship’s wheel, a life buoy, a buildable bell, and a working crane that can lift the vessel’s potato-bin cargo.

The Steamboat Willie set was born out of the company’s fan-generated LEGO Ideas initiative several years ago. Creator Máté Szabó submitted the idea to LEGO in June 2016, then LEGO designers John Ho and Crystal Marie Fontan worked to adapt the set for retail sale, creating decorative elements and the new Mickey and Minnie Mouse minifigures.

Start Your Morning Right With the Alarm Clock That Makes You Coffee

For those who can't function in the morning, a cup of coffee is key. For those who can't even function enough to make that cup of coffee, there's the Barisieur. This innovative alarm clock (now available at Urban Outfitters) awakens the sleeper with the smell of coffee and the gentle rattle of stainless steel ball bearings as the water boils.

Take sugar or milk? There's a special compartment for milk so the liquid stays fresh and cool until you're ready to use it in the morning. On the front, there's a drawer for sugar. The whole tray can even be removed for easy cleaning.

Not a coffee fan? The Barisieur also brews loose-leaf tea.

The gadget also has an actual alarm that can be set to sound before or during the coffee making process. 

This invention was thought up by product designer Joshua Renouf as part of his studies at Nottingham Trent University in the UK. Though the idea started as just a prototype for class back in 2015, Renouf managed to make it a reality, and you can now buy one of your very own.

At $445, the alarm clock is quite an investment, but for coffee lovers who have trouble forcing themselves out of bed, it might be more than worth it. Go ahead, picture waking up slowly to the smell of roasted coffee beans and only having to sit up in bed and enjoy.
