Title: Crumbs (adhesion of food particles to surfaces)
Post by: paul.fr on 05/03/2007 10:40:40
Why do toast crumbs stick to kitchen surfaces, and bread crumbs do not?

I would guess it may be down to differences in the electrical and electrostatic qualities of the carbon in toast (particularly burnt toast) as against those of moist bread.  There may also be differences in the size and weight of the crumbs, and so the forces the adhesion needs to apply.

Have you actually done any tests that confirm that toast crumbs do stick better, or what type of toast sticks better, or whether dried bread sticks better than moist bread?

well it's just an observation at this time...however, i have set an experiment up.

I have four test "subjects"

1. bread
2. very lightly toasted bread
3. lovely golden brown toast
4. burnt toast

i have made three seperate scrapings off all four, which i will check on hourly. scraping one at the first hour, scraping two at the second and scraping three at the third hour.

I await the results.

Cheers, Neil.

I will continue with the experiment any way, hopefully i may win a prize if i publish the results!

As a firm believer in empirical study I applaud your willingness to perform these experiment's.
I am sure the ' powers that be ' will furnish you with a prize...perhaps a Ferrari...or ...a loaf of bread !!

yes, i could maybe then use that loaf of bread to replace the missing crust mentioned in another topic....

well having finished the experiment, you can keep your loaf of bread.

After hours 1,2 and 3 all of the bread and various degrees of burnt toast had failed to stick to the kitchen work surface.

So, i thought that it must only happen when the toast is on top of the crumbs. i then made 3 slices of toat.

1. barely brown, just toasted enough to begin to harden
2. golden brown
3. burnt

i took some scrapings from each slice and place the relative slice of toast on top. after 2 minutes i removed the slices of toast and some crumbs from all 3 slices had stuck to the kitchen work surface.

so, i think it is either the heat from the toast, and or the moisture still within the toast that does ...........something.....

wow, look at that beauty...Karen will have to get up early to win a better pize.

on about lovely cars, i happen to know a song about  cars:

Chim chim-in-ey, chim chim-in-ey
Chim chim cher-ee!
A sweep is as lucky, as lucky can be
Chim chim-in-ey, chim chim-in-ey
Chim chim cher-oo!
Good luck will rub off when I shakes 'ands with you


no not that one..

Here in my car
I feel safest of all
I can lock all my doors
It's the only way to live
In cars

Here in my car
I can only receive
I can listen to you
It keeps me stable for days
In cars


Here in my car
Where the image breaks down
Will you visit me please?
If I open my door
In cars


Here in my car
I know I've started to think
About leaving tonight
Although nothing seems right
In cars

Yes, bad manners come around here most years, the last time i saw them buster was at the bar buying a pint. he was scrimping change...adding the coppers up.

So i ended up buying one for him, i think he must use that ploy quite often

BTW I think it is the heat and the moiture combined which makes it stick!
