Results SummaryWood Takes ~ 3 mins to extinguish at 92 Hz

Petrol Doesn’t extinguish, however forces the fuel to burn faster

Gas Extinguishes within 2s at 91 Hz

Fuel Time Taken Frequency Remarks

Wood ~ 3 mins 92 Hz Flame decreases graduallyPetrol N/a 92 Hz Fuel burns much fasterGas 1s 91 Hz Instant extinction
