WHAT’S HAPPENING?
The foam is back!
YOU WILL NEED
→ 1 test tube
→ stopper
→ liquid soap or shower gel
→ cup of mineral water
→ cup of tap water
HERE’S HOW
1. Add 1 drop of the liquid soap to a test
tube filled halfway with water, insert
the stopper, and shake.
Does the solution foam up?
2. Now add a little mineral water.
What happens to the foam?
You’ll get a lot of foam even if your tap
water is “hard.” And when you add
mineral water, the foam still won’t go
away. Modern liquid soaps replace
conventional soap with detergents that
won’t form insoluble lime soap with the
mineral materials in “hard” water, so
their cleaning power and foam formation
are not affected.
