I came across this page for doing experiments in 2 litre drinks bottles. It got my interest, and I’ve been trying to get my head around which I could do. I like the idea of doing a fun project/experiment at home, and a bottle is small. Initially I was planning to go for the Decomposition one or the TerrAqua one, but then I realised they caused a few problems:-
- They are more complicated
- Require more bottles
- They need holes in the side of the bottles
I’ve decided to make the a bottle fermentation chamber, and make either kimchee or sauerkraut – pickled cabbage. It’s a simple experiment just involving the food ingredients:
- cabbage (chinese one for Kimchee or round headed green one for sauerkraut),
- salt (plus garlic and chilli if making kimchee),
- and PH paper (but you can make your own with the liquid from a red cabbage and some paper).
Sounds good to me, just means I need to buy some cabbage. At the end of it (up to 3 weeks) I will have something that I can eat or keep.
Then I might go onto one of the others. I’d love to do a hanging plant or compost one. We have hanging basket brackets outside, so I could hang them from there, so they won’t have to live in the flat.
Cool! I particularly like the idea of making pH paper – I always found that a bit mysterious and magical at school so it would be fun to repeat the idea with cabbage!
That is cool! I hope you’ll tell us all about it when it comes to fruition.
My dad is a chemical engineer, and he gave us a huge box of pH papers – little tiny slips that measured the pH of things. Maybe a different thing than you’re talking about. But we loved them, and tried to find the pH of every liquid in the house when we were kids.
