TAKE IT FURTHER
Use a turkey baster as a replacement for the straw to slowly layer the colored sugar solutions into a larger glass to create an even bigger rainbow. Hold the tip of the baster against the side of the container close to the surface of the liquid already in the glass. Squeeze the baster gently so the water flows slowly down the side of the container and then onto the previous layer. If you try to rush it, the layers will just mix together. Rinse the baster between each layer. Move the baster upward on the side of the glass as needed so it doesn’t touch the surface of the solution. Layer all the sugar solutions in the same way. This can be hard to do but it’s worth the effort when you finish. Get some pictures!
