The Magical Butter Botanical Extractor is a mechanical device which looks similar to a coffee thermos and is marketed as a tool to infuse food with your favorite herbs.
Sheriff's officials say a Hillsborough County firefighter used one to create homemade cannabis oil.
Deputies were called Monday afternoon to Hillsborough Fire Station 26, a small public safety house at 5302 Thonotosassa Road, after someone found a Magical Butter machine in the workout room with marijuana in it.
The device was powered on and plugged into a wall outlet, according to a report. When deputies opened it, they found a yellow liquid that appeared to be cannabis oil. Two pieces of marijuana were in bottom.
