Why is the sky blue?
My original idea is apparently too close to the truth according to Stud1 but I liked it so here it is...
I'll have a think to see if I can think of something more outlandish today :)There is a thin piece of blue silk between the clouds and the sun. It keeps the clouds and the rain close to the earth and helps protect the earth from the heat from the sun.
Have a great day warping little minds!
