Step 3Twist and Shout
You're going to connect the groups of LEDs in fours.
Get started by connecting two of them. If you've bent the leads all the same way, you can just pick up two LEDs, look at the bottom and orient them the same way, and twist a pair of leads together.
When you're satisfied you've got two connected with the plus of one hooked to the minus of the next, add more LEDs one at a time until you get four in a row. (That's two more LEDs, folks.)
If you're stuck, don't hook just one LED up to the 9V battery as it will not last very long at all. Instead, peer into the LED from the side and look at its internal structure. Just orient each of the LEDs the same way when you assemble them.
Construction tip: You might want to use small needle-nose pliers to twist the leads together without breaking them off or poking holes in your fingers.
