Right then, off we go. Gather round to begin this magical journey...
Step 1: Materials
Eventually you'll get an empty egg. Now we may begin. Get some thumbtacks. Lots of them. Go to Staples or something.
Now heat up your hot glue gun. Get some glue. Lots of sticks. Lots. Seriously.
Good, now comes the tedious part.
Step 2: Begin the transformation
Give it bigger petals, and keep expanding the rings of tacks.
You'll probably hurt yourself. It's ok, just tell yourself that you're a man and you can take it. If you're a woman, this probably isn't for you. Go submit a sewing Instructible in the Craft skills contest. Just kidding. But seriously.
Eventually you'll cover the egg. You have now created something that serves no real purpose. It's freaking cool though. Just don't throw it at your buddies. They'll hurt you, even if their left eyebrow is gushing blood. Try pretending you're the Spartans in the final fight with Xerxes. Where is your god now? Ten-thousand internets if somebody actually makes a Xerxes egg.
Keep it away from pets. Also small children. Don't leave it where people can step on it, or where villains can use it for world domination.
Good luck, and try not to kill yourselves.
