By threading the tubing through a rubber stopper, you can help maintain a good seal with the tin and this allows you to test different arrangements of powder and candle. The tube should have an internal diameter (ID) of approximately 3 mm to minimise powder blowback. My go-to technique involves boring a hole at the base of the tin with a pair of scissors, just wide enough to pass through a 5–6 mm outside diameter (OD) tube. The objective is to end up with a tin that has a hole in the side, with a tube fed through to enable the powder to be puffed into the air above a lit tea light.ĬLEAPSS members should consult SRA002 (bit.ly/3MNbjc3)for different ways of accomplishing this. This makes for a larger flame when it works, at the cost of reliability. CLEAPSS recommends using a small funnel loaded with powder, or running the tube to the opposite side of the tin so the powder is puffed up and back towards the flame. I find that puffing the powder in the direction of the candle (as shown in Figure 1) provides a more reliable, but smaller pop.
