I used this fun recipe to create a sensory bin of sorts for the kids to play in. This rainbow soap foam activity was part art activity, part sensory, part colour mixing science experiment, and all fun!
Rainbow Soap Foam Recipe:
Materials needed:
- food colouring
- water
- Palmolive dish soap
- hand mixer
- optional: glitter
1. In a bowl, add 1/4 cup water, 2 Tbsp. Palmolive dish soap and 5-10 drops of food colouring. I also added some glitter in the same colour as the food colouring to this step.
2. Mix on high with a hand mixer for about 2 minutes, until peaks form.
3. Put the foam into a shallow bin. On a rainy day, you could put it into the bathtub.
4. Rinse the bowl and beaters and follow the instructions again using a different colour of food colouring. Repeat until the desired number of colours are created, adding each to the bin.

When I had made four colours of soap foam, I brought the bin outside and let the kids play and explore with it. They enjoyed mixing the colours and playing with the foam. They tried to use it to paint on the concrete with their hands, but mostly only the glitter stayed visible.
My girls really enjoyed the textures of the soap foam and seeing the different colours they could create by mixing.
They enjoyed every step of this activity from helping me mix the recipe in the kitchen to playing with the finished product.
Even one of our new kittens came over to see what all the fuss was about!
Be sure to have your kids wash their hands when they are done playing so that they don’t get soap in the eyes accidentally and of course, as with all projects, adult supervision is recommended.Â

For this sensory bin, I used a large shallow tub so that I could put the bin on the deck. I used purple gems and added

Doing a sensory bin exchange is a great way to get new ideas too and share what works well with your kids and learn what is working well for others.
At our sensory bin exchange, we each ended up with the makings of four bins.
The kids and IÂ made our farm bag into a bin later in the day. I added a few of our toy animals and the bin was ready for play. I also added a funnel and a small container and lid for pouring and scooping. Granola Girl liked scooping the popcorn seeds into the container, putting the lid on and shaking it to hear the sound it made.
This sensory bin wasn’t originally a frog bin, but I had bought a pack of jump frogs and a pack of kitchen sponges from the dollar store and when I commented that the sponges would make good lily pads, a frog bin was born! We included 



The seashells make great scoops for play. My kids also invented a game of holding one of the pool noodle pieces in their mouth and having others stack the rest of the pieces on top of that piece to see how high of a tower they could create without it falling. It’s not quite what I had in mind when I made the bin, but I like to let them direct their own play!

I have to be 100% honest and say that it was painful for me to watch some of this process. It was painful to watch certain things get mixed together when I knew there would be no hope of separating them again and it was painful sometimes not to offer instruction or give suggestions. I was sometimes cringing when I saw what they were adding, so this was as much a learning exercise for me as it is for them.

Einstein added anything he could get his hands on and just loved the feel of all the different textures. MORE is MORE apparently for Einstein! He added
Snuggle Puppy headed straight outside to gather items for his bin. He had a plan from the beginning and his bin was less about sensory and more about story. He told me to tell my “people that read your blog” that the title of this is “Mommy’s first time camping”. He is obviously excited that I am going to be coming camping for the first time in his life this upcoming summer. He used sticks, twigs, shredded paper, and rocks to create a campfire scene.
Granola Girl started with a very organized bin that can best be described as minimalist but as the time passed, she began to be influenced by her siblings and add some of the things they were adding. She used Kidfetti, an origami box, silk flower petals, seashells, shaped ice cubes, feathers, Easter grass, dyed pasta shells, a ball, a
Dancing Queen’s sensory bin had a distinctive theme of food. She used both real and pretend food. She added corn flakes, mini marshmallows, glass beads, feathers, shells, a wooden heart, flower petals, her pill bottles, and a pretend mango (her favourite fruit), bananas and grapes. She also threw in some red dyed pasta.
