Ordinary ice found to have shocking electrical powers
Scientists have discovered that ordinary ice is a flexoelectric material, capable of generating electricity when bent or unevenly deformed. At very low temperatures, it can even become ferroelectric, developing reversible electric polarization. This could help explain lightning formation in storms and inspire new technologies that use ice as an active material.

Hovercraft Suitcase Gives Your Luggage a Smooth Ride
The wheels on roller suitcases are one of their primary failure points. After the destruction of the wheel mount on her DIY suitcase, [Laura Kampf] wondered if it would be better to dispense with wheels altogether.
To give her suitcase a lift, [Kampf] decided to turn it into a hovercraft so it couldn’t be stopped by pavement or puddles. The first task was finding an appropriate fan, and a compact leaf blower donated it’s body to makerdom for the project. After reducing the blower to it’s constituent components and finding a secret turbo switch, work began on the momentum curtain.
“Nose-holing” the arrangement and size of the holes to pipe air through the stapled tarp and tape skirt seemed to be the bulk of the trial-and-error in this one. Based on other hovercraft designs [Kampf] found, keeping the holes near the center of the inflated portion gave better lift. In the end, the carry-on is able to lift a decent amount even on its lowest setting, resulting in a suitcase that is “not embarrassing” for travel. No word yet on what TSA thinks.
If you’re looking for another unexpected lift off, how about a full-sized flying Delorean replica? We’ve also covered some of the reasons why we don’t see more of these all terrain wonders.
