Sadly, you cannot make lemonade from lemons by pulling the pin on these incendiary pieces of fruit to make them explode. They're inert, you see, and just a side project for tinkerer Chris Myles.
Myles says he created the faux grenades (officially, COMBUSTIBLE LEMONS MODEL 0419) by securing some plastic lemons, paper decals and a "hacked greeting card." A sour sense of style helped too. [Flickr via MAKE]
