quite a cool reaction!

"The movement occurs when the leafs lose turgor pressure, which is the force that is applied onto the cell wall by water and other cell contents, allowing the plant to stay upright. But when it is disturbed by a stimulus, chemicals in the plant force the water to leave the cell. When this pressure is lost the result is a sagging plant. This characteristic is quite common within the Mimosaceae family."
