supermarket shopping cart. The old man had wanted another hundred dollars, but since I was now a partner I did the bargaining, and we got them for twenty bucks apiece, charged and ready to go, with the cart thrown in. Plus three sets of jumper cables, on loan.
Wu rolled the two wire mesh wheels through the shed door. Each went pop and was gone. He put the toolbox into the supermarket cart with the batteries and the jumper cables. He pulled on the rubber gloves, and pulled the wool mittens over them. I did the same.
âReady, Irv?â Wu said. (I would have said no, but I knew it wouldnât do any good. So I didnât say anything.) âWe wonât be able to talk on the Moon, so hereâs the plan. First, we push the cart through. Donât let it get stuck in the doorway where it connects the two aspects of the adjacency, or itâll start to heat up. Might even explode. Blow up both worlds. Who knows? Once weâre through, you head down the hill with the cart. Iâll bring the two wheels. When we get to the LRV, you pick up the front end
andââ
âDonât we have a jack?â
âIâm expecting very low gravity. Besides, the LRV is lighter than a golf cart. Only 460 pounds, and thatâs here on Earth. You hold it up while I mount the wheelsâI have the tools laid out in the tray of the toolbox. Then you hand me the batteries, they go in front, and Iâll connect them with the jumper cables, in series. Then we climb in andââ
âArenât you forgetting something, Wu?â I said. âWe wonât be able to hold our breath long enough to do all that.â
âAh so!â Wu grinned and held up the brown bottle with Chinese writing on it. âNo problem! I have here the ancient Chinese herbal treatment known as (he said some Chinese words), or âPond Explorer.â Han dynasty sages used it to lie underwater and meditate for hours. I ordered this from Hong Kong, where it is called (more Chinese words), or âMud Turtle Masterâ and used by thieves; but no matter, itâs the same stuff. Hand me those cotton balls.â
The bottle was closed with a cork. Wu uncorked it and poured thick brown fluid on a cotton ball; it hissed and steamed.
âJesus,â I said.
âPond Explorer not only provides the blood with oxygen, it suppresses the breathing reflex. As a matter of fact, you canât breathe while itâs under your tongue. Which means you canât talk. It also contracts the capillaries and slows the heartbeat. It also scours the nitrogen out of the blood so you donât get the bends.â
âHow do you know all this?â
âI was into organic chemistry for several years,â Wu said. âDid my masterâs thesis on ancient Oriental herbals. Never finished it, though.â
âBefore you studied math?â
âAfter math, before law. Open up.â
As he prepared to put the cotton ball under my tongue, he said, âPond Explorer switches your cortex to an ancient respiratory pattern predating the oxygenation of the Earthâs atmosphere. Pretty old stuff, Irv! It will feel perfectly natural, though. Breathe out and empty your lungs. There! When we come out, spit it out immediately so you can breathe and talk. Itâs that simple.â
The Pond Explorer tasted bitter. I felt oxygen (or something) flooding my tongue and my cheeks. My mouth tingled. Once I got used to it, it wasnât so bad; as a matter of fact, it felt great. Except for the taste, which didnât go away.
Wu put his cotton ball under his tongue, smiled, and corked the bottle. Then, while I watched in alarm, he tore two plastic bags off the roll.
I saw what was coming. I backed away, shaking my headâ
Iâll spare you the ensuing interchange. Suffice it to say that, minutes later, we both had plastic bags over our heads, taped around our necks with duct tape. Once I got over my initial panic,
