Thanks, but I am not at all convinced.
I'm no expert, though I have had a lot of chemistry training:
As well as I can determine, if you use "hair-dying" grade H2O2, the TATP may have to be dried before being useful because that grade is 6% water. However, if you use food-grade (30%), the acetone-H2O2 solution which also has TATP in it is itself quite unstable and might be able to be detonated without drying. I'm not certain-I haven't tried it. It seems certain that using even more pure H2O2 such as the very dangerous 70+% used in rocketry would require nothing more than mixing and setting it off.
