questions: asked about testing of plastic rice
 
 answers: 1. the water test:

take a glass of water, drop a tablespoon of raw rice inside and stir it for some time. and if the rice float at the top then it is considered as plastic rice, because rice doesn't float on the water.

2. the fire test:

take a hand full of rice and burn it using a lighter. and see whether the rice releases the plastic smell or not.

3. hot oil test:

take some rice and drop them into very hot oil. if it's plastic rice, it will melt and stick together at the bottom of the vessel.
