After the usual chase scene, Jerry accidentally winds up inside a bottle of invisible ink, which was part of a chemistry set. He quickly discovers he's invisible...so the predictable results occur, meaning he uses his new hidden condition to torment Tom. Jerry often is just defending himself, but often he has sadistic streak in him that torments the cat whenever possible, even when unprovoked.Here, he makes Tom think his eyes are deceiving him when cheese from a mousetrap disappears before his eyes, or milk from a dish. Tom can't take anymore so he tries to sleep this nightmare off, but Jerry sets fire to his paw! Man, I hope little kids didn't ideas watching these cartoons back in the '40s and '50s! I always found Jerry, the little mouse, more evil than cute.Thankfully, in cartoons, generally, whatever damage a character suffers is gone within seconds and he's back to normal. The best part of this cartoon is about two-thirds of the way through when Tom figures out what the story is with Jerry, and tries different methods to detect where the mouse is located (such as putting flour on the floor to see his footprints).

The cat and mouse are involved in the usual chases when Jerry dives into a bottle of invisible ink and discovers that it makes him vanish. Instead of seizing the opportunity to go spy on a girl mouse changing room or something, he uses his new-found invisibility to torment Tom. And it's pretty funny and quite inventive despite being a somewhat one-joke cartoon. And the action never leaves the interior of the house, which is usually the trait of below average T&J shorts. Still worth a 7/10.However, I'm not sure how an invisible mouse can cast a shadow on the wall, it defies physics and the very nature of being invisible itself.

The basic joke here is simple. These characters -- all cartoon characters of the era -- are drawn on paper with ink. So using "invisible ink" will make a character invisible. I'm sure this isn't the first cartoon that implicitly plays with the notion that the characters are drawings on a page. (I'd like to know which was the first.) And this is a pretty subtle reference. But we get it without even thinking about it.Other than that, the chases and such are ordinary, most involving techniques Tom uses to make Jerry visible.Ted's Evaluation -- 1 of 3: You can find something better to do with this part of your life.

In one of the usual chases between Tom and Jerry, the latter jumps into a bottle of invisible ink and becomes invisible; he then proceeds to have some fun at Tom's expense. This is a fantastic cartoon, with tons of gags (albeit mostly violent ones, but since when did cats and mice use tact?) and a frenetic pace. Recommended. (Mind you, here's a puzzle: Jerry dives head-first into the bottle of invisible ink, so how come when he emerges it's the BOTTOM half of him that is invisible?)
