You can make a cat bark with that. You'll see your cat go "Woof" in no time.
Tried that experiment involuntarily at home one night. Cooking burgers on the grill, went inside, when I came back outside the grill was ingulfed in flames and the connector hose had burned through. The tank was gouting flame quite nicely, but was not trying to lift off.
Nonetheless, it made for an interesting few minutes.
