If you are doing the experiment with potato or similar (other plant tissue) then you boil the potato you are taking the sample from before you use it, to shoe that the plant tissue needs to be alive for the experiment to work.
Yes you can use other liquids in a bottle rocket. You can use Coca Cola, Lemonade, Soda Water any many other liquids. Just experiment and post your idea on Answers.com.
No.
Osmosis provides the primary means by which water is transported into and out of cells.
The water tank used a reverse osmosis filtration system. Plants use osmosis to obtain water through their roots. Sleeping on a book will not transfer the knowledge by osmosis.
Making a egg drop experiment is easy. You determine the gravity by how fast the egg drops and if it breaks.

Osmosis is the process where water passes into our tissues through a semi-permeable membrane. All of our cells are surrounded by a membrane that selectively allows in anything the cell needs but prevents unwanted molecules from entering. An egg also has a membrane surrounding it so we can use it to represent a cell and see how osmosis works.

Instead of all the liquids mixing together, they form separate layers like a rainbow. They go in order with most dense on the bottom, and least dense on the top. When you do this experiment, you can use food coloring to differentiate the different liquids.
you use an plastic container because it is best to use when doing an egg drop experiment
yes, you can use it in the place of a tooth in an experiment, im not sure why, but I do know that the egg shell has many characteristics of the outer layer of a tooth
they don't use osmosis
where does osmosis occur in the human body?
Passive Transport, and if your dealing with liquids its is Osmosis. Passive Transport is the act of transport with no use of energy: hence the word "Passive." But Active Transport is when it does use energy: hence the word "Active."
One of the most important requirements in the procedure of any science experiment is that you're expected to actually DO the experiment, and then the next step is to take a good look and see what happened. You need to look hard at the egg you'll use for the experiment ... good enough so that you'll be able to remember what it looked like, and spot any changes. Then DO the experiment, and see whether the egg changes. The CHANGES you'll see are the observations.
osmosis involves water passing in and out of the cell
