VOY: Ships In The Night
The crew recieve a distress signal and go to investigate. To their surprise they find the USS Nimitz, hurtling through space at super high velocity, obviously having been slingshotted around a couple of Jovian planets. Upon beaming over an away team in near-warp transport, Chakotay, B'Elanna and Kim find a time capsule inside the ship. So they take it and beam back to Voyager. Upon opening the box, they find:
A Vanilla Ice cd, which Kim takes;
3 Dog Night 8-track, which Janeway takes;
A fake lightsaber, which Tom Paris takes;
Some pocket lint, which the EMH takes;
A thing of Tic Tacs, which Neelix takes;
Preparation H, which Chakotay takes;
A copy of "How to Win Friends and Influence People", which Seven takes.
We see each person deriving great pleasure of their item, and at the end of the program, decide to build their own time capsule.
Tom puts in a video of Chaotica and the Fifth Dimension;
Chakotay puts in one of this rocks;
Janeway puts in a photograph of her husband;
Neelix puts in a special recipe that he invented to commemorate Kes, instructing where to find all of the ingredients and how to assemble the dish;
Seven puts in a vial containing some of her nanoprobes;
While the EMH puts in an isolinear chip containing a video of his medical theories and a demonstration of his singing.
