Video: Aquadoodle pen doubles as capacitive stylus when filled with water
In need of a capacitive stylus for your favorite gadget now that it's cold outside and the capacitive screen is unresponsive to your gloved finger's touch? If you're a parent (or a kid at heart), then look no further than your child's toy box.
If there's an Aquadoodle
(drawing toy that uses water as "ink") in there, then your search is over. Because as long as the Aquadoodle pen is filled with water—and it should be since that's the whole point of the toy—then it will function as a surprisingly good stylus for any capacitive touchscreen. My one-year-old daughter made the discovery on her iPad, but I've taken a wet Aquadoodle pen to the screen of my Samsung Galaxy Tab, HTC EVO 4G, Dell Streak, and iPhone 4 with interesting results.
I don't need a capacitive stylus since it's 73 degrees at 10 p.m. here in Hawaii (and I'm obviously not seriously recommending the Aquadoodle for this purpose), but when I used the pen just for kicks on some of my gadgets, I knew I had to share it.
The pen will leave behind little beads of water, but that's to be expected from a product that uses water as ink. I usually wipe my gadget screens after each use since I don't like seeing fingerprints and smudges, so having a bit of water actually helped to make them squeaky clean. That's what I told myself, anyway.
Since something like this is probably better seen than described, check out the video (720p HD shot with iPhone 4) below.
