Hello 2A-Jay,
Any chance you could post a picture of it?
Would love to see it.
My 31 year old son still has a pretty wicked Potato Gun complete with a Piezo (SP ? ) sparking lighter, made from some special heavy duty PVC pipe. Some serious noise and launch. I could just imagine what your Thunder Mug would do.
Thanks for your replies !
Regards,

P.S. July 4th is coming soon. Problem here is our dog is scared to death of thunder or any booms, including just small firecrackers. Scared to death !!
