I posted this in a closeup magic section too as it refers props. However, this could be of relevance to those who often travel with smoke devices, any anyone who might fly via Singapore. The city state has just completed its ban on these devices. Obviously it is aimed at smokers/vapers - but will hit magicians who are using the devices for smoke generation, rather than just for a habit/addiction. (Though it will hit the latter category too, of course).
I note that Shin Lim comes from Singapore, and though he may reside oveseas now, makes heavy use of the devices in his acts.
FYI - stiff fines and even jail time await repeat offenders.
