My son got this book for his birthday in January (thank you Holly!). We looked at it briefly back then. Now, with schools closed and him at home every day, we opened the book again and are trying to go through as much as we can.
Of course, once you go through the experiments and what you need to complete them, you find out you don’t have half of the stuff. So, this blog is to show you a couple of experiments you can easily do with things you do normally have at home.
At least 30 minutes of a happy kid for each experiment. If you are not too picky with how clean your kitchen is, you can even leave them alone for a while and work, exercise, or sit alone in a room and breathe…
The instructions in the book are a little bit more complete, but what you need is a transparent glass with mineral oil, water mixed with food coloring and a plastic pipette.
We did not have mineral oil, so we used canola. A lot less than they suggest avoiding wasting precious oil.
We did not have food coloring, so we used some old frosting in different colors and dissolved it in water. Yes, it works perfectly! You can even use only water if you use yellow oil.
We did not have a pipette, so we used an old Motrin dosing syringe.
The idea is that the kid puts drops of the color in the oil. It looks super pretty, its hypnotizing, and you can explain all about why oil and water don’t mix. (Oil is made od nonpolar chemical bonds. Water is made of polar chemical bonds. These 2 different bonds don’t mix).
After a while is just for them to play around and mix things – that’s when you can escape.
- You can put a lid on the cup and shake the whole thing to see what happens when everything settles back down.
- Notice the water settles at the bottom of the oil? Is because its density is higher than oil. You can move directly from this experiment to a very easy one where you have a bucket with water and different objects. It is the sink or float experiment: you and the children guess if an object will sink or float before putting it in the water. YES! You can do this in the bathtub as well!
- If there is a water-food coloring mixture left, you can make a batik-painting with kitchen paper. The kitchen paper is dipped into the colored water and absorbs the color. They can turn it around and dip different sides. Leave it to dry and voila! Another decorative piece you don’t know what to do with.
Experiment #2: Candy Rainbow
This is about color science. The book tells you to use skittles, but guess what? Any non-healthy candy filled with sugar and food coloring will do. Additional advantage: your kid uses the candy for the science experiment instead of eating it.
This is pretty simple but super entertaining for the kids. There are different steps to follow:
1. Separate the candy in the different colors (at least 10 minutes of fun, depending on the quantity)
2. Put the candy pieces on a plate making a pattern. It can be lines or circles or a garden with flowers, whatever your kid is capable of or inspired to create (another 5-10 minutes).
3. Use the same dosing syringe from above to pour warm water on the plate
4. See how the water dissolved the candy and the colors start to go out
5. Move the candy around, mix the colors, create new patterns
The book suggests you can repeat with cold water and see what happens. For us, once was enough as it took around 30 minutes. 20 of those I could let him play alone just giving instructions from time to time. Yay!
If you liked these experiments, order the book. I don’t get anything from those sales, but as I am using their ideas, it is only fair to advertise them a bit.
Experiment #3: tubbubble Bath Volcano with a twist
This is not from the book. This is another way of experimenting with tubbubble that is super scientific and fun.
As you know, the tubbubble Bath Volcano is normally used as follows:
Fill the bathtub with water (recommended temperature: 97°-100° F). Open the volcano crater by cutting on the dotted line. Dip the volcano in the water until filled, take it out and be amazed by the eruption of foam and crackling sounds. Repeat.
But there are many ways to use it! One of them is the “bathtub experiment”: instead of dipping the volcano in the water, the kid can pour the bath salts into a container with some water.
The reaction that normally happens inside the pouch now happens in front of their eyes. Foam is created and grows and grows, accompanied by crackles.
(Note: Please ignore awful wall crack!)
See the video to hear the excitement…
After a while, they can throw everything in the tub water and enjoy the advantages of bath salts with organic moisturizing oils and the gentle scent of essential oils.
No. Don’t be afraid of your tub. tubbubble’s colors come from organic gardenia extracts (no artificial or food coloring) that do not stain your tub, your kid’s skin or your towels – science, fun, relaxation without a mess. Just ask them to experiment in the inner corner of the tub so you can throw some bathtub water to wash out the rests without the foam landing on the bathroom floor.
You can visit our “The Science Behind” area on the tubbubble website and share with the kids how foam and the crackling sounds are created. A science class in the tub while getting them cleaned and moisturized.
