Just a curiosity ..... how much cost dry ice in the USA, if you can buy it freely in stores ?
I'm asking for curiosity, cause here in Italy, there's only 2 ways for get dry ice ..... having an industrial licence / special permission that permit you to buy it in big quantities (VERY big quantities) ..... or get it for "transportation of special / pharmaceutical products" ..... in the second way, you can buy "kits" with dry ice and special container for transport, the only problem is that the smallest one that i have found is 20 Kg of dry ice for 102 Euro (125$), and there is no way for get it in smaller quantities or from any store, only by orders .
The only other possible way, here, can be from theatrical / shows supplies, but i don't dare to guess about the prices from them ..... in that field, there is always one or two zeroes too much, at the end of the price tags
I suspect you all don't know what I talk about, so I'll explain. Here in Catalonia, we put tomato to all the bread we eat. I know it sounds strange to you, Sandwiches with tomato, bread with oil and tomato... but it's unimaginable for me to eat a sandwich without it. We are famous around Spain for going to bars and asking them to put the freaking to tomato to the bread all the time, and because people come here and freak out when we serve it to them. In case you have never tasted it, I recommend it to you
