It's a type of low-frequency radio wave which is made of protons. It is a mysterious force which looks like blue-white fire and yet cannot be seen. It's totally weightless, yet it has a small weight.

Franklin, Edison, Thompson, and millions of science teachers should've had a long talk with Mrs. McCave before they decided to give a variety of independant science concepts just one single name. Mrs. McCave was invented by Dr. Seuss.
