When I was a kid, my little brother stole gasoline (from a neighbor’s lawn mower) -- and replaced the stolen liquid with water.
Also, most parents keep a close enough eye on young kids to make it hard for the kid to retain possession / control of something as large as a five-gallon gas can without risk of the parent’s finding out that the kid is in possession of something dangerous—and a kid will probably realize that before stealing a five-gallon gas can.
