It’s Day 4 of reporting but Day 6 of the experiment due to the weekend.

We have decided that this will be our final day of the egg experiment because the egg shell has almost completely disappeared and we don’t think much else is going to happen.

We still want to see if anything else does happen, so we have decided to report on the blog in one week’s time.

On to today’s observations:

* there is a foul odour emanating the experiment

* there are hardly any bubbles inside the experiment

* at least half the egg shell is missing

* the top of the egg is hard – it has also at times not been covered by vinegar

* there is a white substance stuck to the inside of the glass.

’sugar sweet’ -  the shell is starting to peel more and crack

‘curious colours’- the egg is turning softer

‘gear up’- the colours on the egg are turning pale

’slime time’- there is less froth and bubbles than yesterday

’smart metal’- there is no shell on the bottom of the egg.

Overall, the egg shell seems to be disappearing.

We think this is happening because the vinegar may be burning the egg shell.

Where has the egg shell gone? Maybe it is the brown stuff we can see.

On Monday we will have another look.

2 people think it will look much the same.

25 people think it will look a lot different.

Most of us want to find out where the egg has gone- we’ll wait until Monday.

Have a nice weekend.

we saw less froth than Day 1.

We also observed:

* the egg was cracking

* a light brown colour on the egg

* there was a sort of skin on top

* there were fewer bubbles

Some predictions for Day 3 are:

cracked egg

even less froth

colour change to lighter for the egg

egg shell will start to split a lot

Stay tuned for day 2. Will there be more froth?

We placed a hard boiled egg into a clear glass, then covered the egg with white vinegar.

We then observed bubbles forming on the outside of the egg straight away. These bubbles ascended to the surface very rapidly.

Stay tuned to find out what happens tomorrow!
