Talk:1092: Michael Phelps

Jello was actually put into a swimming pool in the pseudo-science TV show "Braniacs".

I wonder whether Randall was aware of the pool experiment (http://research.cems.umn.edu/cussler/pool/). Maybe concrete would be the better choice to slow a swimmer down. BKA (talk) 08:44, 8 August 2012 (UTC)

Would Jello powder dropped in a pool solidify? Does Jello need to be boiled to solidify, or does that just speed things up? TheHYPO (talk) 13:54, 8 August 2012 (UTC)

I doubt the gelatin just added to the pool would work. It needs to be heated to dissolve, and it will melt/dissolve is reheated. But at room temperature, it gels. So I suspect dumping powdered gelatin in room temperature water would just sink. --Blaise Pascal

I don't think heat is required to dissolve Jell-o -- I think it just helps. Agitation (say, an Olympic swimming doing laps) should be sufficient. However, refrigeration helps a lot in gelling, so it'll take quite a while at room (actually outdoor) temperature. Then we have the question of Chlorine, which has a very high pH (very alkali). The acid (low pH) content of some fruits prevents gelling, so they can't be used with Jell-o. It's unclear what effect the caustic would have.

I like thinking that Cueball has four giant boxes of Jello mix somewhere nearby, just to be prepared. --DanB (talk) 15:17, 8 August 2012 (UTC)

It's the Hammerspace! :D --Waldir (talk) 15:48, 8 August 2012 (UTC)

Wow, I didn't know about that! I kinda feel like I'm one of the Ten Thousand today. --DanB (talk) 16:07, 8 August 2012 (UTC)

You're welcome ;) --Waldir (talk) 18:40, 8 August 2012 (UTC)

There is no time scale, maybe between the two pictures, he had enough time to buy it from a store. Hammertime ;) BKA (talk) 09:29, 9 August 2012 (UTC)

Yes, especially since xkcd characters are known to have waited a long time in the same place :) --Waldir (talk) 12:11, 9 August 2012 (UTC)
