Finally got stuck at level Lost-16 – Gunpowder Review

This is a great game. I'm not too wild about the aspect of beating a specific time goal (in this or other games), but fortunately as the levels progressed it seemed to become less of a chore. You don't actually have to beat the time goal to progress, but for some reason I felt compelled to do it. :-) The game does a good job of introducing new gameplay mechanics as you progress in the game to provide some variety, which I appreciated. I almost made it through all the levels, but I finally got stuck on level Lost-16 (from the Bonus Levels 1, Lost Levels set). I guess I probably must be missing the solution, but is it really possible to complete this level with only two barrels and no gunpowder?
