Gravity Bugs Experiment Kit

Going up! Build a mighty robotic bug that defies gravity to crawl up, down, and all around windows with ease! This motorized, multi-legged machine uses an ingenious system of suction cups to walk on smooth vertical surfaces like windows and glossy panels. Assemble the robot to learn about its inner mechanisms, including gears and an electric circuit complete with motor, battery, and switch. Then experiment to see which types of surfaces your Gravity Bug can climb best. Read about how suction cups work and how this robot climbs. This hands-on construction kit brings engineering and physics to life as it demonstrates the power of air pressure at work. A 16-page, full-color manual guides your model building with step-by-step illustrated instructions.

+ Build a small but powerful robot that walks up windows and other smooth, flat surfaces

+ Learn about air pressure and suction cups

+ Third-generation wall-walking technology with advanced suction-cup design

Bought a game and never got around to playing it? Return it, free up the shelf, and put the money toward something you will actually play.

365 days on everything except trading card games. The clock starts the day your order arrives. The item needs to come back unopened and in its original packaging, and you will need your receipt or order confirmation. Email us at Info@OakenVault.com to start a return and we will send you a return label. The cost of that label comes off your refund.

Trading card games get 20 days. Sealed card products are traded as much as they are played, and a year-long return right would let someone buy sealed, wait out the market, and send back whatever failed to hold its value. Twenty days is plenty if you change your mind, and too short to flip risk free. TCG items must come back unopened too. An opened booster has no resale value, so there is nothing for us to refund.

Buying a gift? The recipient has months to exchange or return it, so you can buy early without guessing.
