I just received an item from Hank Lee's called Aqua Bubble Chips. You drop them in water and the water will bubble and steam. However, it came with no instructions. I will call Hank Lee's tomorrow but in the meantime I was wondering if anyone else has used this. And if so, what have you found best as far as : type of container for the water, ratio of chips to water, etc. I can experiment on my own but it's $30 for 2 ounces. So I would definitely appreciate any feedback. Thanks!
