This is a replica of a lemon grenade from the game "Portal 2" where a person named Cave Johnson states: "Alright, I've been thinking. When life gives you lemons, don't make lemonade - make life take the lemons back! Get mad! I don't want your damn lemons, what am I supposed to do with these? Demand to see life's manager. Make life rue the day it thought it could give Cave Johnson lemons. Do you know who I am? I'm the man who's gonna burn your house down! With the lemons. I'm going to to get my engineers to invent a combustible lemon that burns your house down!"
Step 1: Supplies
You will need a fake lemon (About 3 dollars), a fake grenade (about 2 dollars), a hot glue gun, a razor blade, and a permanent marker (optional).
Step 2: Destroying the Grenade
To make the lemon grenade you first need to dismantle the fake one. I kept the speaker and stuff inside for a future project.
Step 3: Removing the Top
To get the top of our lemon grenade we need to remove the top off our fake one. I used the razor blade to do this.
Step 4: Now Put It Back Together
Now you need to put the top back together, don't forget the plunger! You could use hot glue if yours doesn't have a screw like mine.
Step 5: Shaving the Lemon
Now put your grenade top and judge how much you need to shave of, mine didn't need a lot.
Step 6: And Your Done!
You can touch up the part where the grenade and lemon meet with sharpie, or put a Aperture Science logo somewhere but if you don't want to, congratulations you are now a proud owner of a lemon grenade!
Step 7: Finishing Touches
I painted the lemon grenade parts and I added a Aperture Science logo.
