Combustible Lemon

The Combustible Lemon. This combination of words used a single time in the game Portal 2 in a recording by Aperture Science's Found and CEO, Cave Johnson. [link]
Who knew that such a thing would take off in such a way!

I thought of this all by myself. And then, a quick search on the internet revealed that so have dozens of other people.
Let this be a lesson to you, when you have an idea, its probably already been thought of a hundred times over.

Anyway, a simple process. Fake decorative lemons, grenade heads. Drill, Bondo, Insert.
I'm actually a big fan of these grenade heads, the hammer spring is functional - when you pull the pin and release, the spoon flies off. XD

Right. Here it is. Combustible Lemon. Perfect for making your enemies sticky and blind with citric acid and juice.
