Sure, it may seem like a laughing matter (ha!) but the world is facing a Helium gas shortage. Did you know that there’s a Federal Helium Reserve operated by the US government? And that the Helium Privatization Act of 1996 puts NASA and the DoD at the top of the supply chain when it comes to Helium distribution?
So if you’d bought those Helium tanks from the back of a comic book for $1.98 back in the day, you’d be sitting pretty high (ha!) on a valuable commodity today.
