For example, there are three silicone products, first of all, you can use three paper cups to fill the same amount of water, pour the same dose of silicone into the paper cups and place them in the same horizontal position without stirring.

Then select three leaves with a smooth and uneven surface and place them in the same horizontal position, and then select three graduated straws or toothpicks of the same size and put them into three paper cups respectively.

Finally, use three straws or toothpicks to inhale or dip in the same dose of each silicone and drop them on the three leaves respectively, and then observe the following points:

1. See which paper cup is penetrated by the liquid first.
2. Look at which leaves expand wider.
3. Look at the liquid on which leaves dry slowly in the air.
4. See which leaf is penetrated by the liquid first.
