Helium / Sulfur Hexafluoride Voice Changer In A Can

Take a puff and say something. Your voice goes from very high to very low.

Sulfur hexafluoride makes your voice very low, helium very high. Inhaling both at the same time, they'd separate and the lighter helium would come out first and the heavier sulfur hexafluoride would come out last so your sentence would start out with a very high voice and end with a very low voice.

I believe you'd have to have two separate cans and nozzles to get even amounts of each gas in a single serving.

And I've never put an idea in "Other" before. I have no idea where you'd put this. Party favors?
