Nathan -

You wrote about the danger of aerosol containers "bursting" due to strikes 
from Tesla coil streamers. Further, you noted that you have encountered this 
"most often" with spray maint, implying that you have experienced burst 
containers multiple times.

Can you provide more details on your experiences?

1. What was the input power level of the coil, in VA?
2. What was the streamer length that contacted the cans?
3. Where on the can did the streamer make contact (and I assume melt a hole 
through the steel shell)?
4. Were the cans sitting on a grounded metal shelf, wooden shelf, cement 
floor, etc.
5. How many times have you personally witnessed bursting/flaming cans?

If pressurized spray pain cans can indeed explode when contacted by Tesla 
coil streamers, then all coilers who run their coils in their garages or 
workshops should be made aware of  this danger.

I'm very interested in understanding the specific conditions that triggered
