this is challenging but fun!

Level 19, WTF can't do it,

elth,
On 19...
At the very top... place 2 blue orb next to the green one in the middle...
Take the remaining 2 blue ones and place them on the outside of your 2 blue ones at the bottom...
Take 2 green ones and place them below the red ones but ablove the green ones on the sides....
Take 2 red ones and place them on the outside of the silver ones... the ones that stick out the furthest...
Then take your last 2 red ones and place them above your reds and below your greens on both sides...
Then take your last green one and place it between your green ones that go up and down at the top... and the chain reaction will begin!
Good luck.
