Ok a bit off topic but seeing as my consumption of jelly has gone through the roof since being diagnosed it got me thinking it may have been a bad idea I know but it just happens somtimes. So It was I ended up sitting here contemplating my next bowl full and I started wondering . If you made a jelly and allowed it to set cut it into peices and then made another jelly using a little hot water and a lot of cold (thats how I tend to make it any way) and both jellys being of same temperature and identical mix appart from colour (or it would be pointles and stupid) what would happen if you put the set jelly into the liquid jelly obviously the set jelly would not unset as the mix is cold but . Would the set jelly sink to the bottom? Float to the top? Or would it have a neutral buoyancy? Dose the fact that its soliid ish increase the density hence make it sink? Or indeed would It somehow make it more boyant? If so when they are of equal weight and volume how would the mechanism of this work /happen? .

You should be able to make a multi coloured/flavoured jelly by simply making a jelly in the normal way but in a larger bowl than is necessary, once its refrigerated and set make another colour/flavour jelly and wait for it to cool but not yet set and then pour it on top of the first jelly.
The jelly that is already set will remain at the bottom as it is stuck to the bowl and already set, of course jelly is for kids?
Personally I prefer some real Cornish Vanilla Ice Cream with a measure of Famous Grouse Whisky poured over it, of course its only for grown ups :thumbup:

Nothing wrong with adults wanting a bit of jelly now and then! :lol: when I was doing my ketogenic diet I had jelly a few nights a week and really enjoyed it. That said, I'm not *really* an adult until I turn 21 in November, but I can keep dreaming. Not that I'm wishing my life away or anything... :lol:Sid Bonkers said:
Funny thing is I work at a government r&d research laboratory. And still havent got a definitive answer. I have however got a lot of boffins going arround scratching their heads mumbling that they need to buy some jelly this weekend. Answers so far 70% hmm. 20% sink. 10% nutural buoyancy. 0% for float. But no one as yet was either able or willing (incase they are wrong) to give the mechanics of It. The odd thing is they seem to look at me different for asking the question and I dont mean in a bad way.

I shouldn't be intrigued by this, but I am!
Jelly is a semi-solid colloid which is made up of protein chains. In hot water, the bonds holding the protein chains together seperate, turning it into a liquid. As it cools the molecules making up the protein chains lose their energy and rebond, trapping the water into their structure and making it wibbly wobbly.
So, I'm guessing that theoretically the liquid jelly doesn't have a high enough viscosity because of the weaker bonds, so wouldn't support the set jelly.
However, the set jelly would eventually melt again if it was heated for long enough as one of the properties of gelatin is that it is thermoreversible and will melt and reset time and time again.
After all this talk of jelly, I think I need to go and make up a sachet of sugarfree lime and get my fix!

Ok I now have my own hypothesis amd here it is. After some research I have found that jelly while setting neither expands or contracts. There for the density of the solid and liquid are the same ( density being defined as weight per unit of volume. And not as I thought also to do with is firmnes or state of solidity) there for I would have to argue that I should be of nutral buoyancy however having neutral buoyancy the act of placing the set jelly in the liquid would create inertia hence the jelly would gather at the bottom but not because of sinking but but by coming to rest when it natural inertia runs out.

oh wow, i turn my back for 5 minutes and look, a jelly thread!
3 nights on the lake, stinking, havent washed, changed clothes (yes i do mean all of them) have to call the gifls to say goodnight with the smallest of battery life so i use a tiny bit to have a sneaky peak and look, a jelly thread without me! thats just charming!
no jelly for three days and nights now, im getting the sweats
i was dealing with it, now you put it in my head im in trouble
jellyyyyyyyyyy
