I am disappointed in Craig’s new helium scamI thoughtvthat he would be more creative than helium mining in Kansas; like the hottest big scam today: Artificial Intelligence.
There are many subsitutes for helium like hydrogen and argon. Just one substitute for helium in balloons is:
"Baking soda and vinegar create an awesome chemical reaction. The gas from combining the two will cause the balloon to inflate. It's impressive. The more gas there is created, the larger the balloon will get."
