30 Ways to Troll Future Scientists By Leaving Things on Mars

1. $200,000 dollars, a parachute, and the body of DB Cooper.

2. A monolith with a QR code to scan and Rickroll.

3. The missing pieces of the Rosetta stone.

4. An exact copy of the Mars rover (or whatever they use to discover it).

5. A big map of Earth with several points of interest marked on it.

6. I'm a geologist, and I can confirm that just placing the wrong type of rock would fuck up science for like 30 years. I often pick up rocks that I know only occur in specific areas and leave them somewhere that would be naturally impossible in the hope that it will break a geochemists mind when they find it.

7. A NASA spacecraft, one that NASA has no record of. Like something they've never built, but that has NASA logos all over it and clearly has a NASA origin, just not our NASA.

8. A white plastic lawn chair.

9. A brochure about extending your car warranty.

10. A picture of a dolphin waving, and the caption "So long and thanks for all the fish. "

11. A page from a Martian newspaper, pondering the possibility that there might be life on Earth.

12. Flat earth society logo.

13. A fully crewed (by preserved corpses/skeletons of course) Viking Longship.

14. Wacky inflatable tube man on the highest peak.

15. A handbag, containing a disposable camera, a towel and a copy of Hitchhiker's Guide To The Galaxy.

16. A banana for scale.

17. That "S" design we all drew in middle school.

18. I mean… of course a Mars bar wrapper.

19. A set of car keys... imagine that mindf*ck.

20. Soviet era space suit with a skeleton.

21. A whole ass Dollar General.

22. An Egyptian obelisk, inscribe with mathematics relating to something like a spatial fold engine or warp drive.

23. Statue of Liberty half buried in the ground.

24. The fossilised remains of non-human biped with a sign that says "No more nuclear testing".

25. "Welcome to Venus!" sign.

26. A picnic basket, blanket, food laid out with a note - Honey, I forgot the potato salad, I'll be back in 20 minutes - and for good measure, a 1953 Buick. To complete the scene - footprints that walk away and just disappear about 50 yards away.

27. Spirit Halloween.

28. A Cthulhu statue. Just the biggest one I could possibly find.

29. Simple, velociraptor astronaut remains.

30. Liquid water in a mason jar.

31. Even NASA got in on the fun with their official account on Reddit commented on the thread 'taking notes'.
