iCan Party Light



The videos and photos don't do this justice. The human eye has persistence of vision, so the colors "linger" a bit more than the camera can show. What you see above as a single white square is, to the human eye, flashing red-blue-green. Also, the light is brighter and more vibrant to the human eye. It's mesmerizing.

You get a sense of what the eye sees as the can begins to swing in the last video above. There's no camera or editing trickery there; the colors just "separate" due to the motion.

The process of popping holes in the can is fun too; it's better than bubble wrap!

This one is as easy as it looks. You just poke a grid of holes around the can.

To keep the can from denting, you'll want to put holes in the bottom first, then the top ring, and then the sides of the can. Be gentle with the side of the can closest to the top and bottom, since the material there is tougher, and therefore easiest to dent.

When working on the side of the can, I like to start in the middle, since this is the weakest part of the can. If perfection is your goal, then I recommend that you poke a starter hole with a pushpin, then use the slider to enlarge it. This puts less strain on the can, so you're less likely to dent it in. Also, I find that fast pokes do less denting-in on the can.

The technique for putting a half-panel rotation in the can is simple. Insert pushpins in both holes in the sleeve. Remove them. Lift up the can a few millimeters so you can see both holes in the can (each, a "can-hole"). Rotate the can until the second can-hole is above the first hole in the sleeve (a "sleeve-hole"). Reinsert. Gently use a pushpin in the first sleeve-hole to find the second can-hole. When they are aligned, reinsert the pushpin in the first sleeve-hole and through the can. Then insert a pushpin in the second can-hole to better anchor the can in the sleeve, since the original can-holes may now be a bit loose.

Sometimes the drink-hole in the top of the can is too small to insert your lights. You can enlarge the top using the slider as shown in the video. This takes a lot of bit of force, and you have to angle the slider so it hits the wall at about a 45-degree angle, then push in.

The blue light you see in the photos is a finger-mounted LED. The flashing red-green-blue light is a LED bracelet that I twisted inside the can in a helix shape.


Turn on a finger-LED. Enclose it in a ziplock bag. Stuff it partway in the iCan Party Light. Blow in a little air into the bag. Seal it up. Insert if fully in the can. Now float that baby in the pool.

Attach a string of dental floss to the can's tab. Swing it in a circle. If the LED is one of the multi-color flashing kind, you'll get the color separation shown in the video.

The disco light makes a great cover for a homemade nightlight.

Wal-Mart sells a disposable LED light-up balloon for about $0.80 per balloon. You can invert the balloon to expose the imbedded LED device and then pass it into the can. Thread the balloon through the tab of the can. Then pull the activation strip to light the LED for 12 or so hours (then it dies, and you can't replace the batteries). You can either blow up the balloon or hang it from a ceiling or light. You'll recognize the following as a lit version of the photo above:

The disco light looks best with a bright LED, but a softer tealight candle sets a nice mood.
