My Maginificant Methods - hey looks its alliteration

So My new experiment is the 4 different solutions
water and lemon juice
water and vinegar
water and bleach
just Water
I've started my experiment and I'm going to upload some pictures
I said that before didn't i
Okay well I followed this method
1. Using a tablespoon, three tablespoons of lemon juice was poured into a clear cup
2. Using the tablespoon, three tabllespoons of water was poured into the same cup
3. In a different cup three tablespoons of bleach was poured
4. In that same cup three tablespoons of water was poured.
5. In a different cup 3 tablespoons of vinegar and 3 tablespoons of water poured
6. In another different cup 6 tablespoons of water was poured in a cup.
7. The cups were labelled with the different solutions and the above steps were repeated 3 more times.
8. The Copper pipe was cut into sections of 5 cm lengths
9. Each of copper sections' weight was measured and recorded
10. one section of copper pipe was placed in each cup full of solution
11. The above steps were repeated 3 times

So thats the method I followed and after four weeks I am going to again measure the weight of the copper pipe sections and see the percentage difference in weight. I'm not sure which pipes will gain or lose weight

It's now been almost 3 weeks

From my observations the cup full fo vinegar has turned blue. I think is because the copper is disolving.

The cups with the bleach solution have not changed colours but the copper pipes are get these blue solid powder spots. It looks like mutated chicken pox.

I can't even see the copper pipe the lemon solution

The pipe in the just water doesn't look like its made any physcial changes

I am going to upload the picture in 15 minutes
