Trying to teach your kids about science? WildBrain is here to inspire you. We make and broadcast kids’ shows, including classic favorites such as Teletubbies, Caillou, Yo Gabba Gabba!, Kiddyzuzaa and many more. As a part of that mission, we provide resources to make your parenting journey a smooth one. 

This week, we’re celebrating the launch of Season Two of Hydro and Fluid – a show about the (mis)adventures of two runaway water molecules. Every episode of the series features a few fun science experiments that help our heroes figure out how their world works. 

We took a note from their book and put together a list of fun science experiments to try with your kids. Enjoy and be sure to check out the official Hydro and Fluid YouTube channel for more playful science and a hearty laugh.  


 1. Laundry Party 

This trick will make chores instantly fun. All you need is laundry detergent in either powder or liquid form and a UV light bulb. Simply switch it on and be hypnotized by the surreal, blue glow of your previously-boring box of Tide.  

How does it work?
Washing powder/laundry detergent glows under UV light due to the presence of phosphorus and other whitening ingredients in it. Try this with your kids and they’ll end up looking forward to laundry day. 


2. Lazy Gardening 

For this old trick, you’ll need a piece of cotton cloth or thread, a jug of water and something you’d like to get wet – say, a houseplant. Simply place one end of the thread in the flower pot and the other deep inside the water jug. The trick is to make sure that the jug is placed slightly higher than the plant, and you’re good to go. You can also try this with two jars of different-colored liquid to make things even more spectacular. 

How does it work?
The water will soak the thread or cloth and eventually reach the other container. The thicker the conductor, the faster this happens. 


3. Instant Rainbow  

For this experiment, which really sounds like a superpower, you’ll need a transparent glass of water, natural light and your little ones’ favorite drawing materials. Place the water glass on a piece of paper in direct sunlight and watch as a rainbow forms in front of it, much to your young artist’s amazement. Now just step aside and let their creativity run free.  

How does it work?
Because water has a different density than air, it causes the rays of light to bend at different angles, which creates different wavelengths – or colors – of light.  


4. Magic Float 

Our plucky heroes love to play around with discovering which objects float or sink. Probably the best experiment of this kind is the saltwater one. 

Start by filling a jar or measuring cup with water to about two thirds of the way. Add salt until you get the right concentration for an egg to float and when it does, watch your kid’s eyes widen with awe. You can even turn this into a game by adding objects of different weights and trying to guess whether they’ll float or sink. 

How does it work?
As the salt dissolves, it increases the weight of the water. This makes it denser, which, in turn, allows more objects to float on the surface.  


5. Custom Flowers 

As a bonus, here is a super-simple experiment from the brand-new second season of Hydro and Fluid. You can watch it on the official Hydro and Fluid YouTube channel.

For this, you’ll need 5 white flowers (any kind you like), 5 vases and 5 different shades of food coloring. It’s important to use food coloring, as other dyes may be toxic to the flowers. Just fill the vases ¼ of the way with water and add 10-20 drops of food coloring. Trim the stems at an angle before putting a flower in each vase, let it sit for a day and voilà!  

How does it work?
Plants absorb water from the ground, which then travels up their stems to reach their leaves and petals. Even though our flowers have been cut, the stems still draw water and spread it to the petals, along with the color, producing spectacular results.  


The brand-new season of Hydro and Fluid promises many more fun science experiments, so be sure to check it out on the official YouTube Channel.
