When i left, takehome something bright and blue, really cool. I went delivery picking, you should know if you ever come to england, britain, you have to suffer because you have to bend down, picking strawberries on the floor, cut to pieces, so easy and this country. It is like cheating. And blueberries fall in which i connected gallons, an american writer, not prejudiced toward this sort of thing, put the sugar and stop boiling it up and i am sure plenty of you made it and this is not what happened. What happened is you that the boiling process happen and what you put in stark blue comes out, bright fuchsia pink which is weird and it is not blue. Blueberries i got home and told everybody was blackberry jam. It is wrong so six month later back in the uk i had a friend who directed history documentaries and he was making a documentary about the 16th and 17th centuries and these are women in every village, the midwives, picked up the pieces we used for jobs so they wrote down, they were systematic and these were things that kept coming up and im curious to know, they are not testing for witchcraft which they thought they were doing, something is going on. There were two things he showed me. One of them was a thing that said if you boil the first water of the morning, which is urine and go through all the colors of the rainbow, someone is bewitched, i think i was bewitched if i tried it and it would be if it werent. On one of those things, the beanery is one of those bright colorful flowers that you get in the summer. In this neck of the woods as well. And put it on someones skin and it changes color, they are bewitched and i had to think about this and it turns out a bright red cattle and they the pigments that make them, the bright vivid colors are chemicals and they are really interesting. You get red cabbage, not all but a lot of the bright vegetable pigments are in this and the interesting thing is they act as ph indicators. If you are ever bored, get some cabbage, throw it away, and it will be bright red and you can go around the kitchen, it is highly entertaining because it changes color. If you put it on something else, it goes blue and alkaline goes yellow and green or acid things and goes red. Change it and it all depends on the time you boil it, a huge range of colors and so i worked out your sweat can change ph depending on what you have been doing, your genetics and so after if i pedal boiling water on my skin normally it didnt change, but if i did it, i spent a while trying this, they change color. So wise women were testing for was they had a ph indicator and they were testing the ph of peoples sweat so we did this tv segment and then i rumored the blue ones 6 months beforehand because as any of you will know, when you make it, what goes in a pound of blueberries and sugar and juice and the reason is it is the entire thing is litmus paper for the lemon juice so i didnt stand a chance but it was almost worth it for that little thing. That is what i was doing. You can watch this and other programs online at booktv. Org.
