This is just an 💡💡Idea 😃

Spinning bottle

1. Steps to follow

1. It's a major step to choose a  right bottle🍶it might be a plastic bottle .
2. Cut it half and pour some water in it might be half  ensure that the cap is fitted very tightly
3. It's a shot introduction:.   Inside itself there should be motor arranged with a fan in it.and a small battery to power the motor and a switch to turn on circuit the fan will spin the water in side it and the bottle itself must be spin even with a small torque with being with equilibrium.

1.  problems in building it

1. when the motors spinning the water and bottle gets spins up the bottle gets excess for the bottle is accessing the one bottle then get unstable and I get fall immediately. So fill appropriate amount of water in it.

   

   This is a diagram showing my idea

2. The motor should be placed at write place or might be centre of the bottle
3. The cap of plastic bottle should be some what convex not completely only very very small.
4. It would be good science experiments demonstration
5. Try to place the battery and motor at the centre of the axis or cente of gravity as they are heavy the may cause disturbence
6.
