At work we got stuff for checking if a weld has a crack or not. It\'s a two part process with a dye and a developer. Well... if you spray (they both come in airosol cans) the developer on something that doesn\'t have any dye around it, it turns into a cool frosty snow! Just thought i\'d share. i\'ll try and remember to not the name on the can tomorrow so you can try it out. Maybe i\'ll frost up a base at lunch or something when the boss isn\'t looking
