Thermal Detonator props

Hello, I'm new here etc. etc. etc. I did a search but couldn't find anything, so if you know, I'd be obliged...
I'm working on building my arsenal of model weapons, and was wondering if anyone knew how to make a hardware or otherwise cheap thermal detonator model.

thanks,

Here's a nice tutorial.

 

That's the only tutorial I know of. I was going to post it but I was beated to the punch. Any one know how to add sound to one of those?

 

well for sound your going to need sound electronics

 

No kidding.



But ones that are small enough, inexpensive enough, and make the right noise, those are rather tricky to find as it may seem.
