Spelling Words with Rising Bubbles

Inspired by a Jeep’s falling water display, Matt Bell created an Arduino-based bubble display, which turns Jeep’s idea on its head. Matt’s latest version makes a few key improvements that help with the bubble size and steadies the speed at which the bubbles rise. For consistent bubble movement, Matt recommends using mineral oil and keeps each “bubble channel” (as I like to call it) in its own vinyl tube. We’re looking forward to seeing the improvements that the next version brings! [via Arduino]
