Depends, If you keep the leaves(?) on it and put it towards the back to act as a stabilizer it may work a lot.
Also the ease of leaving the barrel may depend on how ripe or how unripened it is.
Less ripe, and more hard, may require more pressure to leave the barrel.
That may result in further distance and power, but may cause a kB.
IMO;
You may need something better than hair spray to get the pineapples going.
Propane anyone?
