The colour was very bold to begin with and didn’t show dramatic colour change until the final cup. When I combined the samples together, the resulting tea had a mostly fruity taste with some acidic notes. - Kira K.

For the coffee I had to run the experiment tow times as the filter has torn. The second time I have used both a sieve and a filter (I have shown a photo of the experimental set).
*NB: I haven't labeled the photos and the tables to get more room for the text and pictures and to be able to use larger font. Neither have I labeled the cups as it is easy from the color of the filtrates to identify them (it is obvious that the darkest colors correspond to the shortest times).
