My hand fell on the button of my 'watch' and the portal snapped open with a small 'fwip' sound. Tama paused to look at the sudden hole of darkness.

And I pounced.

My arm swept around, the half-meter wide hole scooping the turtle off the lantern like an interdimensional bug-catching net. Another button press and the portal closed with the critter trapped inside.

"Ha!" I grinned, then paused as I stared at the stone lantern. There was a large chunk of it missing now, a smooth, circular section of it scoured perfectly out of existence. Right where I had taken my swing.

I tapped the lantern with my foot. Solid stone...

Ouch... Now I had a visual to go with why Washu told me NOT to open it part way through people or load bearing structures. I mean, damn! I hadn't even felt resistance, and the portal just cut through that lantern like I was taking a swing at thin air. I could take a swing at a support column for an office building and drop the whole thing on my head more efficiently than the best demolition teams on the planet.
