hey buddy,

first thing about RP. you or anyone must not touch that in hand and it must be coverd very safely. the procedure is use carbon paper cotton rubber from all this u have to cover it . and when you perform Rice test.

the rice will move zigzig and mark the lenght.

once its start pulling it will change the colour once it reaches the bowl it will become ash.when you touch it.

when you use tourch . use big torch means with big cells and not the small cell battery. that wont give good result and use bulb torch, not the LED torch.

when u test the cells will become soft and if u open it will be like cream.
