“Finding Water On Mars As An April Fool’s Prank. Every April Fool’s Day, which is the first day of every April, we all try our hardest to prank and pun each other. All this is done for fun and laughter. According to “Universe Today,” not even big science hotshots like NASA are above a few harmless pranks. Never was this more obvious than in 2005, when NASA pranked the world about finding water on Mars. On March 31, 2005, a teaser was posted on NASA’s Astronomy Picture of the Day website. It was titled “Water on Mars!” with a presentation to follow the next day, on April 1. This left people ecstatic. This was an incredible find for the human race. If there was water on Mars, then that meant there could have been life on Mars at one stage. Science was about to make a huge leap forward. The next day, April 1, 2005, NASA posted their presentation of water on Mars, and it left the whole world either in tears or crying from laughter. Their presentation was a picture of a glass of water standing on top of two Mars chocolate bars. It was water on Mars, but not the kind that everyone was hoping for.”
