Colour stacking experiment...

Luey was DYING to try this water stacking experiment at home. Luckily all you need is food dye, a clear straw, some salt and some water in glassess... The first glass/colour, should have no salt. The next should have half as much salt as the third glass. That way the colours won't mix in the straw...

Here is Erik demonstrating how you stack water...





We discovered it helps to have different levels of water in the glasses, with the lowest level in the first glass you're collecting water from, and the highest in the last. This allows the water to rise to a higher level in the straw with each colour.
