MAKE blogger Sean Ragan created this provocative kit enabling you to make a medical replica out of nothing but Lego, with the exception of one slightly modified piece. Build the syringe by following the easy “order-of-operations,” using red for blood, or maybe a blue medicine from the future, or create yourself a sickly yellow-green poison. Complete your work of art with a single drop of Lego, seemingly pouring out the end of the needle.
