Science gone wrong

Wednesday, April 6th, 2011

After Tyler got a volcano for Christmas, he has been fascinated with the concept of overflow so Paul showed him and Anna the Diet Coke/Mentos videos on YouTube. That was a mistake. A big mistake.

Paul and I bought a couple 2 liters of pop (yes, POP) and a pack of Mentos on a Sunday while the kids were at their mom’s house, then waited for the kids to return to us on Tuesday after school. Apparently as soon as Paul picked the kids up from school, Tyler was begging to do the experiment. If you have ever met Tyler, you know he is um…persistent. [he gets that from me--until it becomes annoying and nagging. that he gets from Paul]

Paul called me as I was driving home from work. He was desperate for me to get home so he could get relief from Pester Tyler. I insisted that they wait for me to get home b/c I wanted to take photos. Paul wanted to knock out the experiment before it got dark. We compromised: I sped up and Paul hid in the bathroom away from Tyler. As soon as I walked in the door I grabbed the camera, Paul grabbed the ingredients (minus a couple Mentos that did not make it past snack time).

I was too late. Paul told Tyler that he could not drop the Mentos in his 2 liter b/c he was wearing an NC State shirt. Of course Tyler refused to change shirts and he was beside himself and in complete meltdown when I got home. It didn’t turn out like that on the video that’s for sure!

 

 

Any Nerds Out There?

Wednesday, April 7th, 2010

I saw this today and thought it was pretty cool. I think there are a couple other nerds that read this but I guess we will find out :) .

´╗┐Scientists have found the first multicellular animals that apparently live entirely without oxygen. The creatures reside deep in one of the harshest environments on earth: the Mediterranean Ocean’s L’Atalante basin, which contains salt brine so dense that it doesn’t mix with the oxygen-containing waters above. Previous samples taken from the water and sediments in the basin showed that single-celled life was present, but a new study published this week in BMC Biology has identified multi-cellular animals that apparently live and reproduce in the sediments under the salt brine. Italian and Danish researchers describe three new species of tiny animals called Loricifera. The animals took up radioactively tagged leucine (an amino acid), and a fluorescent probe that labels living cells, evidence that they were alive when they were collected. The researchers also found examples of individuals that contained eggs and evidence of apparent molting, which led them to conclude that the animals spend their whole lives in the harsh sediments. The creature’s cells apparently lack mitochondria, the organelles that use oxygen to power a cell. Instead they are rich in what seem to be hydrogenosomes, organelles that can do a similar job in anaerobic (or oxygen free) environments. The find could help scientists understand what life might have looked like in the earth’s early oceans, which also had very little oxygen.
