Toshi: "Tae, lift very gently, or bubbles break.
Tae: "OK,but my hands get covered with soap."
Gentle wind is good for making big bubbles.
Toshi: "Oh! Great!"
Tae: "I can make a lot of bubbles."
Toshi: "That bubble is so big that you can almost put your head into it."
Tae:"Next, I'm going to do with this hunger frame."
The soap on the hunger frame produces huge bubbles one after another.
"I try to stick my arm inside this bubble."
Although it is quite difficult, you can stick your arm into a bubble.
It is so striking to see large bubbles rupture suddenly.
Required time: You may need three hours for the entire experiment
(from preparation to clean-up).
Children may want to continue until all the liquid is gone. If you don't have enough time, make less amount of liquid.
You simply mix the three kinds of liquid (water, detergent, and starch). Then it's ready to use!
This particular bubble solution is toxic. Please do not make bubbles by blowing using straws or other blowing implements.
I am neither a scientist nor a school teacher. I am just a mother of three children. I feel very happy when I and my children are together working on science experiments. We are only doing quite simple experiments, but those give us such enjoyment. We often like to do these experiments repeatedly. When you read a science experiment book, you may already feel that you master the subject simply by reading it. But you can understand much more if you actually try experiments by yourselves. When my children and I work together on experiments, conversation starts between us. We learn together and have fun together. I think these moments are so precious.
