yep, I've ignited it using two AA batteries and tried it again with a couple of D batteries. Line the two batteries up end to end like you're placing them into a flashlight. Hold a part of the SW to the negative end and then touch the wool to the possitive and poof, it's smouldering. Needless to say, it got added to the trucks kit. <img src="images/graemlins/cool.gif" alt="" />
