Tektites are amazing little rocks thought by scientists to have formed when rocks from space impact the earth - either as a meteorite or a comet. There is a lot of speculation as to their origin. They have a glass-like make up that might be mistaken for obsidian.
These wonderful little pieces of outer space rock are millions of years old - from 2-3 million to 34 million years! Imagine!
This neat little package includes one tektite measuring from 1 inch to about 1-1/2 inch and a card with educational information on the back.
