"It's funny that you should have to condense electricity," said Herb, with a twinkle in his eye. "It's just the same as milk, isn't it?"
"Yes, it isn't," said Bob. "Another wise remark like that, and you'll find yourself out in the wide, wide world, young fellow."
"I should say so," said Joe. "That was a fierce one, Herb."
"Well, I'll promise to be good," returned Herb. "But I still think that was a pretty fine joke, only you fellows haven't got enough sense of humor to appreciate it."
"We've got sense enough not to appreciate it, anyway," said Jimmy. "It's weakened me so that I'll have to have another piece of chocolate to brace me up," and he suited the action to the word.
"When you've all had all the candy you want, we can go ahead and make this condenser," said Bob. "Don't let me hurry you, though."
"No chance of your hurrying me," replied Jimmy. "I'm so all in now I can hardly move. But Herb and Joe will do anything you want them to. They've been taking it easy, right along, so they shouldn't mind working a little now."
"Jimmy has done more work to-night than I've seen him do altogether in the last six months," said Joe. "So we'd better let him rest himself awhile now. He's apt to get sick if we don't."
"Well, I guess this paper has soaked up all the wax it's going to, so we can go ahead with the rest of it," said Bob, as he started fishing squares of impregnated paper out of the saucepan.
He laid one sheet on one of the blocks that Jimmy had cut out, and on top of that laid a sheet of tinfoil, then another sheet of paper and one of tinfoil, alternating in this way until he had a number of sheets lined up. The little tabs or projections on each sheet of tinfoil he arranged in opposite directions, so that half of them could be attached to a wire on one side of the condenser and half to a wire on the other side. Then he placed the other wooden block on top of the whole thing, passed the four screws through, one at each corner, and tightened them up evenly. This squeezed all superfluous paraffine from between the plates, and held the whole assembly very securely and neatly.
