A container filled to the brim with explosive fluids is no laughing matter, although the LEGO Head Propane Tank might make you smile upon seeing it.
It may or may not be a coincidence, but it happens that regular propane vats share the same overall design and proportions as LEGO heads. So it makes sense that Instructables user icedvovo has posted a detailed guide on how to precisely modify your fuel tank to look like a loveable inhabitant of LEGO Land. The result is the cute, familiar look of the LEGO Head Propane Tank.
About $20 worth of spray paint and some enamel hobby paint is all that stands between you and your perfect barbecue. Just don't let your guard down -- albeit cute, that thing could blow up at any time!
