Best Answer

The pop-up umbrella works because there is a middle ring connecting to the ribs when you push down on the ring the umbrella pops out in to a protection cover. The original umbrella worked because the ribs are connected to a ring that is connected to the middle part of the umbrella and it slide up and down that to open and close it.

What color reflects heat best for an outside umbrella?

White light is made up of all the different colors of light, as can be seen when it is separated into these various wavelengths using a prism. The colors that we see are the wavelengths of light that are being reflected off of the objects we are looking at. Objects that are red will reflect only red wavelengths and will absorb the other wavelengths; objects that are blue will reflect only blue wavelengths and will absorb the other wavelengths; etc. Black objects absorb all visible wavelengths of light, which is why black asphalt gets so hot in the sunlight. White objects reflect all wavelengths of light. Therefore, a white umbrella would reflect the largest amount of light. However, this does not necessarily imply that it would be the best color to use for an umbrella because what really matters is how much light is transmitted through the umbrella to reach the shade below. The more light that gets through, the less effective the umbrella is in providing you with shade. Therefore, what really matters is how opaque the umbrella is, rather than what color the umbrella is. The opaqueness will be more characteristic of what material the umbrella is made of than what color it is. The fraction of the light that is transmitted will equal all the light that strikes the umbrella that is neither reflected nor absorbed. Thus, it is best to find an umbrella which combines high reflectivity with high opaqueness (generally a thick material) in order to keep the umbrella from heating up and stop the greatest percentage of the sun's rays from reaching you.
