In the 1930's scientists had to go to a mountaintop where cosmic rays were common in order to smash atoms. Now scientists use atom smashers called particle accelerators to accelerate particles to high speeds and collide them with the target atoms. All they need to add to have a fantastic lab is this great sign!
This is a brand new sign with the following features:
12" x 12" screen printed on caution yellow
Sturdy .032 aluminum sign with rounded corners
Drilled hole for hanging
It features a picture of an atom
