Answer 2

hi dear,
if you wanna make a physic model then you can go for a burglar alarm. It is very simple model just you have to do is to prepare a model of the house having floor made up of thermocol. The floor must be designed in such a away that one end (+) of the wire which is already connected with the battery, that is kept under the floor touches the base of the floor at the entrance. The second end (-) which is connected with the battery should be kept in such a way that it just arranged above the positive terminal. Thus when anybody will press that part then alarm will get activated......?

How about duplicating the rings of Saturn? You will need a round mixing bowl, a fairly large one, a solid, spongy rubber ball, water, a tea spoon and some course black pepper. Fill the bowl to about two inches from the top, using the spoon, stir the water in one direction until a vortex forms in the centre, place the ball in the vortex and sprinkle the pepper into the water, the pepper will form rings around the ball just like the rings of Saturn. Remember to clean up after your experiment.

Answer 4

Take a pitcher jar packed with water positioned a small decrease out of a few thing like a diver or submarine out of a marginally stiff cloth; which floats partly, like rubber or rexin. Then tie the mouth of the jar very very tightly utilising a membrane, like a decrease balloon. Press and pull the membrane and the decrease out will pass up and down

Answer 5

How about a catapult? Couple of pieces of wood, a spring, and a small metal rod (long screw will do), and you have something that can throw a ball several meters.
