Algodoo

Enrage your pancakes with the pancaker - a gun that shoots angry pancakes!

Mag goes on top, sliding in from the rear, triangular piece on the left hand side.
The grip folds out, drag the polygon under the barrel down to unfold.
Remember to turn the safety off before firing, the sliding rod should be under a red circle.
The trigger is bright orange, for convenience.
Magazine can be released by dragging the dark gray part down.

Disclaimer: No actual pancakes will be provided

Have fun!
