Mysterious Chemical X grows plants curiously fast - prank!

Step 7 Wakey Wakey, eggs & bakey, & 8 hour grown monster vegetables?

1. Drag your reluctant mark out of bed, you don't want them too on the ball.
2. Explain how since you planted them together, you should inspect them together too.  For incentive add on the fact you couldn't help notice little green things poking up when you walked bye.
3. When there jaws stop dropping reach into the tray and pretend to separate the leafy clippings from one of the vegetables and take a bite. 
4. Pretend to choke a little then mumble something like, "Oh-No, the chemical  X".  Don't leave them hanging too long or it could actually be frightening.  Then say April Fool's!
    

Note - It actually took a while to explain that this was an April fool's day prank, she couldn't shake the fact the chemical X was make believe.  When she put 2 and 2 together she laughed for quite a while, although she did promise revenge.  Awesome.  As a bonus, you now have some yummy veggies to saute for dinner.
