Kiddie helium balloons will soon cost $100 each according to Cornell scientist Robert Richardson.
Why?
Helium is used in radiation portal monitors to scan for bomb-making components entering the country, and the proliferation of these devices after 9/11 is causing a shortage, reports Popular Science.
The upside is that at $100 per balloon it would cost $9,900 to release 99 of them making the accidental start of World War III cost prohibitive for hippies.
