I love these founatins. Always a crowd pleaser...

Don't quote me on this, but I think the propellant is NC or at least NC-based, which would account for the lack of charcoal spray/firedust and the weird chuffing sound they make. They're also choked.

Not sure about the stars themselves but I vaguely remember someone saying they were also NC-based. Not sure quite how this would work in therms of binding, colourants (chlorides?) etc... Would love to hear some input on this... Never thought about silicone...

I've only seen one fountain with a similar effect, which interestingly was choked like an organ pipe and made an even more pronounced chuffing sound.
