I know this doesn’t have anything to do with building but after reading this forum for a few years, there are people participating in this forum who know all kinds of weird stuff.
I need to know the approximate hardness of Jello in technical terms. I am comparing this to some silicone dielectric gels which have a Gel hardness,g of between 65 and 120
many thanks

We need to know the color of the Jello first.

*Jello brand or some generic house brand ?That new sparkling stuff or the old stand-by ?
*If hardness is an issue just pack more in.Theres always room for Jello.............
*Damn it, I thought you could only use the reichter scale to measure Jello.BTW not a good question for a Sunday nite for a bunch of atheist like us.....Gabe
*Factoid: Did you know "Jello" is the Swahili word for "Calves hooves"?
*Although Jello is a colloidal protein and therefore a "gel", it grows mold long before it fully cures, so I can't see anyone wanting to test it for hardness. But I'm sure some university students must have tried it, maybe the websites of a couple of your local colleges have Q addresses you could tap ?
*No, but seeing as that is one of the ingredients of gelatin, it would make sense.
*On the Moh scale, it's i No Moh!
*What timing! Just yesterday I completed my thesis, "On The Durabilty Of Colloidal Substances As Road Base". From exhaustive tests, paid for with taxpayer's monies, I have concluded the average hardness of 1-3 day old jello is 4 as measured on the Rockwell C scale. Yellow is .75n; green is .12n; red is .13n. Curiously, a 4:2:3 mix yielded an average mean hardness of 7, which exceeds that predicted by computer modeling probabilities.This is good news. I have always said I won't ride a motorcycle again until the roads are made softer I guess I should be dusting off the Harley sometime soon.BTW
*I got to swim in a pool of green jello for a multiple schlerosis fundraiser thingy--sweet hide glue, you say? Got a T-shirt and a sticky car seat.
*The answer lies HERE! These guys know all bout Marshmallows, jello can't be much different? Joe H
*Are we talking regular dessert-quality jello, jello with embedded pear slices and cherries, finger jello or jello shots? We can't offer a really qualified, quantified answer without specific formulaic data. Furthermore, while I applaud your attempt to find a replacement for silicone dielectric gels during this critical national silicone shortage using common kitchen ingredients, this is a job best left to real scientists, like us.
*You need to specify additional parameters as two instant gelatines with different bloom strengths will exhibit different characteristics. For example, the final hardness of each gel type and thekinetics of the hardening process (slope of the curves) of an acid-basedproduct with a bloom of 270 to 310 differs from one with a bloom of 220 to260. The higher-bloom instant gelatine begins to harden almost immediately,while the lower-bloom product hardens after three to four minutes. A similarproduct of different particle size shows the same traits; however, hardeningdecelerates as the mean particle size distribution increases, and finalhardness is reduced despite the same binding time. The final hardness and the gel-forming kinetics depend on environmentalconditions and technological factors. The pH of the medium is of particularimportance. Gelatine and instant gelatine's isoelectric points (IEP) vary withthe manufacturing process. Acid-based gelatin has an IEP between pH 8.5and 9.0, while that of an alkali-based product is in the pH 4.8 to 5.5 range. Because gelatine molecules are positively charged above the IEP andnegatively charged below it, they exhibit differing types of behavior dependingon the pH of the matrix. For instance, type A gelatine is relatively stablewithin the pH 3.0 to 6.0 range, and hardness is reduced only at highervalues. Conversely, type B tends to lose gelling power as pH falls. Interactionwith other ingredients, especially other polyelectrolytes where the charge isdependent on pH value, also affects the performance of gelatine.(Most of the preceeding is plagerized...)
*As I recall. pH is the negative logarithm of the effective hydrogen ion concentration; so, acid would be less than 7 and alkaline would be greater than 7.
*It depends on how long you leave it in the fridge with the fan on after camp. By January it tends to become crusty.
*Joe H said: "The answer lies HERE! These guys know all bout Marshmallows, Jello can't be much different?" Joe HI checked it out and that must be funniest site on the Internet. Laughed myself silly. Also check out the links at that site, along with the Twinkie page. http://www.twinkiesproject.com/RoseBTW, lest anyone think my *factoid* was truth, it isnt'. The Swahili word for Calves Hooves is, well, actually it is *Twinkie*. Yes, that's it. I'm sure of it.
*I knew it, I knew it, you guys are just a bunch of vultures waiting to jump on some dumb butt question!!Actually, even though I don't make a livin at construction now, and I can saw a straight line, really, I also do that electronic thing. And what I am doing is changing a projection tube in an old Mitsubishi tv set. There is a silicone gel between the face of the picture tube and the first lense. This gel is an optical coupling as well as a heat sink and the gel on the old tube tore as I was removing it, so I need to replace it. Well they don't use a gel much anymore and nobody will fess up as to where to get it so I located some clear gels from Dow Corning. The original gel is about the consistance of Jello. (new, fresh, lime, Oreo cookies optional, well actually not as lime Jello demands Oreos) But the data sheet on the available silicone gels is specified in "g" between 65 and 120. So if I know what the "g" of Jello is, shazam-I know where I stand re: silicone gel.You guys bored yet?anyway many thanks.
*try http://www.loctite.com and send them a note - they're usually pretty good at matching potting gel
*I am making cherry jello as I Break....will email with new cybertransporterport.near the wiggley stream,ajI do play volleyball Wednesday with a friend who regularly mixes batches of polymers for paper mills that are thickened with some acid PH change nonsense to me but sounds like whats posted above yak...He is online...have your man email mine...
*OK, now that we know what the need is... instead of jello, which in my experience tends to wiggle around at the slightest provocation, you might try to get your hands on one of those discarded breast implants. Plenty of gel in there to experiment with.Now, seriously,dielectric gel, etc.
*I am afraid if I ever got hold of some I couldn't let go!!Actually I think I have it solved, just waiting for cost and availablity of some Dow Corning gel.Many thanks to all
*Years back used to buy silicone fluid from Dow Corning, and it was sold as a clear liquid by viscosity (thickness), measured in centistokes. Water is about 1, 10 weight motor oil is about 50. Jello is in the neighborhood of 500,000 based on my memory. We once had some 1,000,000 stuff sent to us in a glass jar. During shipment the jar broke, but the stuff was so thick it hadn't had time yet to leak out by the time we opened the box.Hope this helps. Looked quick on Dow's site and found this information on silicones; maybe it will lead you to your material:http://www.dowcorning.com/fs.pl?filename=11gen%5Finfo%2Ehtml&path=%5Cdow%5Fcorning%5Chtml%5Cindustries%5Celectrical%5C561Rich.
