Aluminium Fire Trick (update) – one minute survival tip

This time: Don´t burn your fingers!
Some have already tried this trick, and burned their fingers. So it’s time to show the trick again.
Cut a strip from the aluminium foil of 10 cm and fold it in half lengthwise, in order to make a kind of butterfly bandage. Leave a thin “bridge” in the center of the strip. This is the most common mistake: the bridge is too wide, nothing happens. The bridge should be exactly 2 mm wide, not more or less.
