Obviously, pushing down on the nipple
sticking out of the turret releases a catch and the rubber band is supposed to
send the flame 'tongue' shooting-out, on mine the band has lost a fair deal of its
original power so it's not exactly an instant action!
Once fired the tongue just lolls there
until you push it back in, looking as realistically like flames as my foot! But
it was only a cheapie rack-toy , which is why it also sometimes catches on the
'lips' of the mouth and doesn't fire at all.
Not the best .gif I've done, lighting's
poor and it's a bit jerky, but it gets across the action!
