"A dream. It's perfect": Helium discovery in northern Minnesota may be biggest ever in North America::For a century, the U.S. Government-owned the largest helium reserve in the country, but the biggest exporters now are in Russia, Qatar and Tanzania. With this new discovery, Minnesota could be joining that list.

Probably not much. The hydrogen that a party balloon would contain could certainly make a small, exciting explosion, but it probably wouldn't have enough energy to set anything else on fire.

It's a common high school chem lab demonstration. Without added oxygen, the H2 balloons sort of burn from the outside in, and you get a sort of slow burning mushroom plume. It could light paper or cloth on fire in close proximity.

With added oxygen... BLAM! It could shatter windows.

You willing to risk your house, life, and the lives of your children in that?

Yes. I use flammable gas for cooking and heating in my home everyday, hydrogen science kit toys are available for children to play with, and I have some experience working with actually dangerous high pressure hydrogen and oxygen to boot.
