Having found some distilled (aka de-ionised) water in our fantastic local shop that you go to if you don't know where to get something from, Jayline, we were able to proceed with another experiment from our big science book. Having got a red cabbage in our veg box and cooked most of it, I kept the outer leaves and a bit more of the stalk than I would usually discard and boiled them up in the aforementioned water. After it had cooled down, I drained the water off through a sieve into a jug and it's now in a bottle in the fridge awaiting use as an indicator of pH.
We are also in the middle of undressing an egg, it's been sitting in a glass of white vinegar for about 33 hours now (renewed once this afternoon) and where we've carefully rubbed the remains of the shell away you can just see through to the yolk now. It should be naked by tomorrow afternoon (we're off in the morning to Fun Club and won't be home until mid-afternoon anyway) and then we can see if the membrane really is permeable with some food colouring.
If I'm allowed, as both K & M have taken against me putting photos 'on blog', I'll post some photos with the continuation and results of our kitchen science experiments.
The renewed interest with the Walking With... (Dinosaurs and Beasts) videos (yes, really, we still have videos here) is continuing and we watched two more episodes....again!
