A cheap substitute for the stun gun is a piezo-electic gas-grill igniter (looks like a spring-loaded sparkplug). They go for $5 or so – however I’m sure the stun gun would give a more reliable spark. Love the see-through idea! Does anyone know if they can ignite a toy rocket-motor? That would add a lot of “go” to the spud.
