“We all know the plan, right?” Tim said.

Rachel put her hand up. “I am still a little fuzzy on the whole disappearing act we’re doing.”

Pru jumped up, running up the stairs with glee. Robert looked after her with a playful disgust. Then he turned that disgust on Rachel. “Did you just ask that so Pru could do her little demonstration? We’ve said—we shouldn’t enable her.”

Pru came back down the stairs with a bowl full of water. There was a model boat bobbing around on the top of the bowl. She placed it in the center of the table. “Here’s one I made earlier. Now, this is all very simple. It all has to do with swimming pools.”

“Swimming pools?” Rachel said, feigning confusion and ignoring a side glance from Robert.

“Yes. Interning for a spa company, I was able to learn certain tricks. And while I was there they were perfecting something—something which is pretty commonplace now—the invisible pool. My company was trying to figure out how to make swimming pools a little less...roomy. You got a whole room for a swimming pool and not much else. You can’t entertain in that room, especially if you don’t want to go swimming. So, they had the idea—what if you could have a swimming pool that’s not so permanently on display all the time. What if it was invisible, hidden, and could just become a swimming pool when needed. Right? You have a swimming pool under the floor. Then the floor lowers, leaving pockets where the water can flow through. The floor goes down and down, revealing the pool. When you’re done swimming or sitting or peeing in the pool, whatever, you press a button, and the floor comes back up. Same thing happens, but in reverse. The floor has enough drainage to let the water pass through it. The floor rises and the water goes from on top to underneath.

“I wondered if maybe I could do the same thing but in reverse. I wondered if I could create something, suck the water out, and create...let’s say, a room. Then we could get rid of it at a moment’s notice. Flip a switch and the room is gone.” Pru picked up the little toy boat. It had an extension on it that didn’t match the main boat’s color. It created an extra part of the boat.

“Roomy,” said Rachel.
