Does quicksand really exist4/13/2024 I was truly excited to read and review this novel, Quicksand, by Swedish author Malin Persson Giolito. In Mad Max Beyond Thunderdome, a horse Max is riding collapses from the heat of the desert and then sinks into the sand in the part of the film after Max is ejected from Bartertown.“No one asked if I wanted to save Sebastian, but you all blame me for failing…” Poe's original fate was rewritten so he was ejected some distance away from the dry quicksand and reappears later. In Star Wars The Force Awakens the TIE fighter Poe Dameron and Finn use to escape crashes and when Finn wakes up the wreckage sinks into the sand and, he assumes, Poe. In 1999's The Mummy Rick, Ardeth (Medji), and Captain Winston Havelock crash their plane in the desert and the Captain dies and sinks along with the plane into dry quicksand. In Hotel del Luna's episode 3, Jang Man Wol falls into dry quicksand. In The Princess Bride, Buttercup falls into dry quicksand, and Westley jumps in to save her. In that scene, there is no evidence of water. Lawrence's servant Daud dies when falling into quicksand in the desert. ![]() With no water nearby, it is likely meant to be dry quicksand. In Miss Fisher and the Crypt of Tears, Phryne Fisher begins to sink in the Palestinian desert and calls out that she is sinking in quicksand. In Indiana Jones and the Kingdom of the Crystal Skull Jones and Marion end up stuck in a dry sandpit. The large plates at the end of legs of the Apollo Lunar Module were designed to reduce this danger, but the astronauts did not encounter dry quicksand. The successful landings of the unmanned Surveyor probes a few years earlier and their observations of a solid, rocky surface largely discounted this possibility, however. ĭuring the planning of the Project Apollo Moon missions, dry quicksand on the Moon was considered as a potential danger to the missions. Indeed, reports that travellers and whole vehicles have been swallowed instantly may even turn out to be credible in the light of our results. In nature, dry quicksands may evolve from the sedimentation of very fine sand after it has been blown into the air and, if large enough, might be a threat to humans. Objects are known to make a splash when they hit sand, but this type of jet had never been described before. Lohse also observed a "straight jet of sand violently into the air after about 100 ms". Lohse found that a weighted table tennis ball (radius 2 cm, mass 133 g), when released from just above the surface of the sand, would sink to about five diameters. They then turned the air stream off before the start of the experiment and allowed the sand to settle: the packing fraction of this sand was only 41% (compared to 55–60% for untreated sand). Writing in Nature, physicist Detlef Lohse and coworkers of University of Twente in Enschede, Netherlands allowed air to flow through very fine sand (typical grain diameter was about 40 micrometers) in a container with a perforated base. In 2004, it was created in the laboratory, but it is still not clear what its actual prevalence in nature is. Historically, the existence of dry quicksand was doubted, and the reports of humans and complete caravans being lost in dry quicksand were considered to be folklore. Dry quicksand can also be a resulting phenomenon of contractive dilatancy. It acts similarly to normal quicksand, but it does not contain any water and does not operate on the same principle. ![]() ![]() Please help improve this article by introducing citations to additional sources.ĭry quicksand is loose sand whose bulk density is reduced by blowing air through it and which yields easily to weight or pressure. Relevant discussion may be found on the talk page. This article relies largely or entirely on a single source.
