It´s fun :)
We recently got into experimenting, at home as well as at the school front.
We tried the milk-foodcoloring trick that, by the way, also works with pepper on water, and while we had the pepper out, we did the good old separating-salt-from-pepper- trick (with a balloon, by using static energy).
We put a candle out by using a glass, and then by putting the candle on a plate with water, and the glass over it - if you don´t know what happens then, well, try :)
We mixed natron and citric acid on several occasions, for filling balloons or letting rockets fly, and of course I dug out my old favourite - the lava lamp.
I ordered some ferro-magnetic fluid on amazon, and we played with it in water:
This effect is really neat, and you can view much better results in this video:
You only have to really take care to get this stuff on anything - it hardly comes off.
By now, my sons are pumping air into bowls with water and flooding the kitchen as soon as I don´t look, and the kids in school are asking me when my next experiment comes, and I´m feeling like I´m slowly running out of them. It´s hard to find impressive experiments that are not dangerous in front of large groups of kids... I´d like to get my hands on some dry ice:
See? I said it´s cool.
Liquid nitrogen also looks very interesting, but is apparently not safe to use in class, either - but watching this video makes me really regret being a responsible adult:
Now, aren´t those "self-inflating" balloons extremely cool? That was my small excurse into science. If you happen to have any further experiments I could use - cheap to perform, safe, but still with a surprising effect - don´t fear the comments-section.
The most beautiful song I´ve listened to within a year, hand´s down. Nothing to consume on heavy replay, but something to listen to maybe once, or twice a day, to bring you down on your knees and gut you. And listen closely to the mandolin solos. And don´t forget to breathe :)
