WANTED: HELIUM

Lindsay Morris

Wanted For:

Helium is used as a cooling medium for the Large Hadron Collider, the superconducting magnets in MRI scanners and NMR spectrometers, and is also used to cool satellite instruments, and the liquid oxygen and hydrogen that powered the Apollo space vehicles. Also, because of helium's low density and very low reactivity, it can be used for filling decorative or toy balloons, weather balloons, and airships.

IF YOU SEE THIS ELEMENT, REPORT IT TO THE AUTHORITIES IMMEDIATELY.
