Why and what ?
The project is a part of an experiment which I've made with my son. This is relaxing toy which shows some physics basics (like not mixing oil with water, and how waves are created) Great project to spend time with kids. It is very easy and gives really nice and fast effect before the kids could get bored.
Here is the video showing the whole making process with the final result:
The project is really easy.
Take the cup, pour the water to it and then add some colour. This will be Your 'sea' in the bottle. You can use any type os stain from food stain (good idea, it gives transparent sea) to waterpaints (sea won't be transparent).
Now take the transparent bottle (could be glass or plastic) and pour the coloured water to it.
The final step is to create the 'atmpshpere'. Pour the olive into the bottle. Try to fill it with 1/3 of coloured water and 2/3 of oil.
That's all. Now the toy is ready.
