Carl's Jug O' Boom (you can put stuff in it)

Carl’s Jug O’ Boom
Type: Incendiary Tossable

Effect: When lit and tossed, results in a small explosion, followed by burning splash damage over a wide area. Flames will burn for 15 seconds per level of attacker’s level of Incendiary Device Handling Skill.

Status: Inert until torch is activated.

Created by an unstable, pantsless man who talks to a cat, Carl’s Jug O’ Boom takes the bigger-is-better approach when it comes to hobgoblin fire bottles. Burns hotter, bigger, and faster than your normal Molotov Cocktail. The use of a standard torch instead of a cloth wick makes these devices much more stable. Just don’t drop it once it’s lit, lest you find yourself doing a Joan of Arc impersonation.

This one, is hollow, and has screw threads between the parts, so you can put things in it.

The Fire  of it, is from this model (toss them a like/boost for  a great fire model):
