You are given two jugs, one with 3 liters capacity and one with 5 liters capacity, an unlimited supply of water, and a salt tablet. The salt tablet produces a 100% salt solution when dropped into one liter of water. The challenge is to produce different concentrations of salt solution.
Click left of the salt tablet to drop the tablet into the left jug; click right of the tablet to drop it into the right jug.
Displayed under each jug are the number of liters it contains and the saltwater concentration.
Click one of the blue arrows above the jugs (representing taps) to fill a jug with water.
Click one of the blue arrows below the jugs (representing drains) to empty the jug.
To pour water from one jug into the other, click one of the green arrows.
If the water in a jug contains any salt, it is displayed in pink, otherwise it is blue.
There are 36 challenges of increasing difficulty.
You get a win message when you have created a saltwater solution with the correct solution.
