A whoofle is a short pyrotechnic display that is a mainstay of Big Clive's live streams. The device used to produce whoofles is called a Whoofler. Whoofles traditionally happen on stream every hour on the half hour, i.e. at minute 30. They are often—but, unlike Jägermunions, not always—in tribute to someone.
A whoofle is performed thus:
- Affix the whoofler (a funnel-like attachment) to a spraycan of butane gas.
- Put a few drops of washing-up liquid in the whoofler, then dilute them with some water.
- Press the whoofler downwards (on the flare around the bottom) to add butane gas from the can. Release the whoofler (while still holding the can) when the bubbles have created a small heap above the cylinder, but before they flow over the edge of the whoofler.
- Ignite the concoction.
Clive periodically flame-proofs the ceiling with borax in his streaming room to ensure that his whoofles produce no lasting structural damage to his house.
