https://padlet.com/alexanailea30/58qgmunkvhz Needed: 1 egg. Vinegar. A plastic container with lid. Process: Fill the plastic container with enough vinegar to cover the egg completely. Introduce the egg inside the container. Close with the lid. Wait 48 hours (take the opportunity to take a weekend trip). Take out the egg and watch how it bounces (CAUTION: if it is pulled from a lot of height the egg breaks). Explanation: As noted, the egg has increased in size and has become elastic. What has happened is that the vinegar has reacted with the shell of the egg dissolving it and, in a reaction called osmosis, the water of the vinegar has passed into the egg through the semipermeable membrane that covers it. The egg becomes elastic by that remaining membrane. en-us 2019-01-18 18:29:47 UTC 2019-01-18 18:51:00 UTC hello@padlet.com alexanailea30 https://padlet.com/alexanailea30/58qgmunkvhz/wish/322267344 2019-01-18 18:47:53 UTC https://padlet.com/alexanailea30/58qgmunkvhz/wish/322267344 alexanailea30 https://padlet.com/alexanailea30/58qgmunkvhz/wish/322267784 2019-01-18 18:48:44 UTC https://padlet.com/alexanailea30/58qgmunkvhz/wish/322267784 alexanailea30 https://padlet.com/alexanailea30/58qgmunkvhz/wish/322268508 2019-01-18 18:50:10 UTC https://padlet.com/alexanailea30/58qgmunkvhz/wish/322268508
