did you try doing that..what if you succeed...will you change your opinion :) ?
OK anyways...with a normal toilet flush maybe no... but with an extra pressure of buckets full of water applied with thrust..maybe something is possible..atleast you can experiment..and let us know the results..(as far as my experimenting with kitchen knife..i dont need to do all this...i believe in following the proceedings of investgations
Also is it possible by any chance that it was not flushed through the commode but through the drainage next to the toilet...there is a metal plate with holes which connects the bathroom drainage......I am not saying this is the way it was done....but there are different possibilities..and people are trying to explore them...toiling hard to find out based on a simple confession instead of laughing over it......and you are just ridiculing and saying everything is false... what a difference in attitude!
