very interesting, cheers Ben!

Professor Bronek Wedzicha has it sorted!
I like it! I like toast!

But it dosen't say how thick the marmite has to be

Grim! LOL!
Well, I would use the marmite to stick the flapping sole of my slipper back to the top bit! As thick as that!

Room temperature, about a teaspoon, spread thinly on the hot, buttered toast immediately so the Marmite begins to melt into the butter

Everyone remembers the Tickle Toaster but no-one seems to remember Jon's other breakfast idea - the Pritt-Stick Butter. I'm sure it's mentioned in Live Updates somewhere.

"the butter should be used straight from the fridge, applied unevenly within two minutes of the bread coming out of the toaster."

This would make Jon's idea of the staggered toaster obsolete.
Two minutes is plenty of time to butter two slices of toast.

The Pritt-Stick butter is easily improvised, just cut the end off the wrapper of the block of butter.

According to my book of 100 whacky inventions the pritt stick butter has already been done
