An interesting kit that combines the science of milk with a bit of artistic creativity. Projects explore things like surface tension, and our favourite - using the clumping properties of the casein in milk to make glue or a plastic-like molding compound. Families report varrying degrees of success with the projects, but that kids loved the activities regardless often repeating their favourite projects over and over again. Does require several other supplies to do some of the experiments: vinegar, toothpicks or cotton swabs, glue, string, salt, soda, a hole puncher, and plastic lids. Parents loved that the instructions include simple child-friendly explanations of the science behind the activities. 




It was so much fun. My favourite was making the sun catchers. I want to keep mine forever! And I like that I can do some of the experiments and art by myself. I want to do them all over again.



My favorite was the suncatcher because it is super duper easy. Just have to squirt glue and add food coloring, let it dry and then it was done. It was so much fun. One of them didn't work but I still think it was super cool. I didn't like the one where you squirt the food coloring into the bowl and you put the paper in. Some of the experiments didn't work but it was still a lot of fun. They should make more experiments.



This science kit is small but you can do a lot of things. It is a cool science kit because you use milk and you put stuff in and it changes colour. Mine was different than my sisters (4) because she is super messy and I am not as messy. When you put in the drop of soap it looks like it is exploding. I like mixing the milk with the food colouring to make amazing crazy pictures on paper. My dog ate one of my papers when it was drying outside. I wish the paper was bigger to make bigger pictures and there was a marker so I could draw on the cool backgrounds.

Zahra(F8) did the first project with Daddy. She quite enjoyed getting to play with the "messy stuff", food coloring and dish soap. We had seen the YouTube video how to do this experiment but the kit was an easy way to make the idea come to life. She did also make a painting from the food colouring on the thick card stock type paper included in the kit. They colors were a bit light but she was happy with it. I thought the kit was a bit pricy until I thought about the price of food coloring - so it's an ok value. There are still two experiments and there is lots left. It's and educational, sensory, family , messy fun time.

This is a nice compact science/ art kit. It has almost everything you need to make some cool experiments. The instructions are small but that isn't an issue, I wish the instructions were in colour to better illustrate the projects. We had a great time (M7 & F4) creating cool designs and making mixtures.

F6 is very interested in science experiments and crafts so this seemed like a good kit to try. Idea is unique along with the use of milk for experiments. Came with most of what you need (food coloring, liquid soap, heavy pieces of paper for the craft). Some of the experiments did not work out as expected and we were going to retry them but ran out of time. Their favorite was the sun catcher craft which required glue. All the pieces fit back in the small milk carton shaped box that it came in. Still requires parental help to do the activities.

A perfect gift for a science loving kid! We love how the kit is in a milk carton shaped box and the packaging and name are very attractive. My kids couldn't wait to try out the experiments! The kit contains food colouring x 4 and a bottle of dish soap, and some special paper. The instructions are very easy to follow and offer experiments to do at home that requires ingredients everyone would normally have in the home already. When the kids asked "how does it do that?!", I was able to read them the "how" right from the booklet! We tried the first experiment of squirting food colouring in milk and adding a drop of dish soap and all 3 kids m9, f7 an f5 were amazed at the swirls and movements of the colours. We also tried dipping the paper into the food colouring on milk and made some cool artwork. We tried doing the salt water experiment where you pour water and food colouring mix into salt water. I think I poured it too fast and the colours didn't get to separate from the salted water. We also tried the cola experiment, filling a full cola bottle with milk and watching the cola become invisible but it's been 3 hours and the mix is still a light brown milky colour and the milk has not settled at the bottom. I used 2% milk. I imagine that whole milk might be required or make a difference? There are still a few experiments left to try, including a suncatcher and making glue. The kids really like this kit. It could be a much cheaper kit if they didn't include food colouring and dish soap as most people have these already. I felt that if they were able to provide these things, they could hae also thrown in a q-tip and some salt. I told m9's teacher about the kit and she seemed enthralled and is looking into trying some of the experiments in the classroom. For science or art!

The kids absolutely love it. I don't know how much science they actually learned, but they really had fun with the experiments and the art. How successful the experiments were is another story. Some were definitely easier and had better results than others, as well as faster. And surprisingly, the experiments worked well with soy milk as well as 2% milk (except for the plastic milk experiment). I am bothered by the name of the kit. "Just add milk" implies that you really don't need anything other than milk. Nowhere on the kit does it say that you'll need additional supplies (vinegar, toothpicks or cotton swabs, glue, string, salt, soda, a hole puncher, and plastic lids) to complete the experiments. Most of these supplies can be found around the house, but since they're so inexpensive, I don't see why the can't be added to the kit (except for the soda and the hole puncher, of course) by the makers of "just add milk" kit. They could remove a couple of sheets of the heavy paper or downsize the food colouring bottles to offset the price of the "extras" if necessary to make it more complete. The good thing is that the kit provides enough food colouring to do all of the experiments and art many times. The kit promises an entire afternoon of fun. Half of the experiments / art are pretty fast to complete... the other half require a day or more of waiting. Because the kit doesn't come with anything I don't already have around the house (food colouring, paper, and liquid soap) and I still have to provide a lot of the required ingredients for the experiments & art projects, I would expect to see more than just 4 experiments and 2 art projects in the instruction booklet. But the kids really do love the kit, from beginning to end.

Lily (5.5) and I had fun doing some of the experiments outlined in the booklet that came in the package. We tried it with 2 different types of milk - 1% and her brother's 3.25% milk. We noticed differences in the results based on the milk type, which was pretty neat! It worked well and although the explanations in the booklet were a bit advanced for Lily, I was able to explain them in a way for her to understand. Details: The differences we noticed between using the 1% milk and the 3.25% milk were that, originally, when dropping the colours of dye into the milk, the dots of colour were more concentrated into smaller areas of the 3.25% milk than the 1%. Also, when we added soap, the colours swirled much faster in the 3.25% milk. This was also true when we used the tip of a straw with soap on it to push the colours around. Finally, when we actually made art with it and put the thick card stock paper into the milk, it was much darker and more colourful on from the 3.25% milk. We guessed it might be because the 3.25% milk has more fat molecules in it!
