Hello everyone, I am a recreational toker. So in my free time, I like to go around and see new products that I can turn into a bong. I was in Walmart the other day and I stumbled upon these miniature vases. I was looking at them and realized I could turn these into a bong. I looked on the bottom of the vase and it said Reactive Ceramic. I'm not sure what that means. If anyone knows what that means and if I were to turn it into a bong, would it be poisonous smoking out of? Thanks, jetspwn
