I'm a big Portal fan, and I've been wanting to make my own lemon grenade ever since I spotted this one last year. That one has a soundboard in the display base, but mine makes a "tick-tick-tick BOOM" sound when you pull the pin and press the handle, which is a fun little extra. (Here's a quick video of it in action.) It's a simple mod that shouldn't cost you more than $10 in materials - not including the display - and only requires a few hours to do.
(You can also see this tutorial on my blog, Epbot, where I have a few extra process photos - and I'm actually giving away one of my two lemon grenades over there next week, so feel free to mosey on over if you'd like a chance to win.)
Ok, let's get started!

This is a simple mash-up of a toy grenade with a fake lemon, so obviously you're going to need a toy grenade and a fake lemon. :) I found my grenade (which comes with the speaker and sound effects) at a costume shop for $2.99, and the lemons are from Wal-Mart and I think cost about $2 each.
Other than that you'll need a small screwdriver to disassemble the grenade, a thin utility or craft blade, and beading pins to hold the two pieces together. Oh, and also a Dremel to drill the holes for the pins.
If you want to paint your grenade topper as I did, you'll also need matte black spray paint and some painter's tape.

This is pretty awesome. One question though, are the wires exposed around back or do they go through the lemon? I didn't see you mention it and I imagine it would be hard to get it around the cement in the center but I was just wondering.
As for the wires, nothing is exposed, and nothing has to go through the center of the lemon. The wire only reaches from the top of the battery casing to the speaker, so the excess wire is just wrapped around the speaker and tucked inside the grenade cap - you can see it a little in my photo where I'm holding half of the cap in place.
I hope that makes sense - it's always so much easier to show with photos than it is to explain with these pesky "words" and such. ;)
Yeah I sometimes have trouble finding the time as well. I'm trying to streamline things by uploading pictures on here the same time that I upload them for my blog, and then by trying to make them similar enough that I can just copy/paste my posts into instructable form.
You could use one of those "Real-Lemon" plastic lemons. They are actually yellow, though much smaller.
