On this occasion we have made some balls of gel. It is not a very big experiment, but to do with 2 children of 2 and 4 years, it is better to do an activity as simple as that. They had a great time, and they took their balls home from memory. I think the balls did not last long after that.
EXPERIMENT MATERIALS
For this experiment you will only need a few balls of gel, which you can buy in any virtual or physical store.
EXPERIMENT STEP BY STEP
This experiment has been very simple, almost do not say the step by step:
1) Take a few balls. Beware of taking less than you think, because then they take up a lot and you may run out of water.
2) Put the balls in water, and wait for them to absorb the water.
3) They look at the balls in the middle of water absorption, to see how they are going.
4) It takes a few hours until the balls are completely complete and have absorbed the water. Because of the refraction phenomenon, it will appear that they have not absorbed water.
