There was a peculiar warmth to the stuff. Maybe it was radioactive. But
no, it was too light to be one of the heavy elements. I tossed it back
to the table top and then nearly rose to the ceiling. The stuff hadn't
bounced with a metallic sound at all, but had settled slowly, coming to
rest with no sign of a bump.

I picked it up again and looked at Jud, puzzled.

He grinned and said, "Watch this." Then he looked at the lump of metal
in a peculiar manner like he might be trying mental telepathy out on it,
and suddenly the stuff weighed a ton. It forced my hand down so fast
that it bruised as it struck the table. As suddenly the stuff became
light again and Judson Taylor had hold of my hand, rubbing it.

"Oh, I'm so sorry, Bill. I am not too good at controlling it yet."

"What the hell IS that stuff?" I ground out.

"I don't know, exactly," he replied. "Mallory, the biochemist, made it
and brought it to me. He said he got a lot of chemicals spilled. One of
them was a rare enzyme that he didn't want to lose, so he mopped up the
mess and put it in a large flask and added some alcohol, getting ready
to recover this valuable enzyme. Suddenly this stuff started to form on
the sides of the flask, just like silver in the mirror coating process.
But all the chemicals were pure hydro-carbons with no silver or other
metal present. According to Mallory this stuff is some unknown
hydro-carbon. I've been playing with it for two days now."

Judson Taylor put the stuff back in his pocket and rose.

"Let's go over to my lab. I want to show you some things I've found out
about it."

I gulped down the rest of my coffee and followed him. We crossed the
campus of good old Puget U to the antique building which housed the
physics department. We climbed the creaking stairs to the third floor
which was devoted mostly to Jud's own private research and was filled
with apparatus that he had accumulated during the thirty years he had
been kingpin of this department.

Jud crossed over to a bench on which there was a balance and some other
stuff and placed the hunk of mystery on one tray of the balance. On the
other tray he placed a ten-gram weight. The balance swayed a little and
then came to rest on the zero mark, showing the stuff weighed exactly
ten grams. Then he placed another ten-gram weight on the tray and the
balance came to rest on the zero mark, showing the stuff weighed exactly
twenty grams!

"Now watch," he said. He placed the
