Hi everyone This is my first post so please let me know if i do something wrong. My problem is in the Wizard of Oz when the witch appears out of no where... i need instant smoke but cannot put a smoke machine due to no power and lack of space... I believe i saw some beads a while ago that claimed to produce instant smoke when broken, has anyone every heard of or used these? if so do you know where i can buy them online or in AUS? I'm open to any suggestions you guys and girls have thanks very much Jack If you need more info i can get it for you.
