The 11 Year Soap Bubble
-Overdrive- writes "Popular Science has an interesting article about an inventor and his 11 year quest for Colored Bubbles" From the article: " It turns out that coloring a bubble is an exceptionally difficult bit of chemistry. A bubble wall is mostly water held in place by two layers of surfactant molecules, spaced just millionths of an inch apart. If you add, say, food coloring to the bubble solution, the heavy dye molecules float freely in the water, bonding to neither the water nor the surfactants, and cascade almost immediately down the sides. You'll have a clear bubble with a dot of color at the bottom. What you need is a dye that attaches to the surfactant molecules and disperses evenly in that water layer. Pack in more dye molecules, get a deeper, richer hue. Simple. Well, on paper anyway."
Also, I noted that the article referred to soap bubbles as "the world's most popular toy". Here is an interesting question for all of us: what is actually the world's most popular toy, and how do one measure it? I'm willing to bet a good amount soap bubbles isn't the correct answer...

Your to late for the ketchup idea.
Since 1952 the US Government has been testing ketchup. Ketchup must flow between 3-7 centimeters in 30 seconds to be considered Grade A. Ketchup that flow closer to the 3-centimeter mark receive better scores. Ketchups that are too thick or too runny receive poor grades.
They have a video on their website of what these things look like:
