Instructions to make TNT (trinitrotoluene):

A beaker of 76% sulphuric acid, 23% nitric acid and 1% water.

A beaker of 57% nitric acid, 43% sulphuric acid.

In percentages of weight, not volume. Remember, it's easier to make a big explosion than a smaller, more controlled one.

10 grams of the first beaker are poured into another empty beaker and put in an ice bath, making beaker A.

Add 10 grams of toluene and stir for 8 minutes; clockwise for 40 counts, counterclockwise for 40 and repeat.

Remove beaker from ice bath and heat till 50 degrees celsius; solution is constantly stirred while being heated.

From the first beaker, add an additional 50 grams and allow the temperature to rise another 5 degrees. Keep constant for 10 minutes and an oily liquid forms on the surface.

Return this acid solution to return to the ice bath, cooling down to 45 degrees celsius, the oily surface will sink to the base, when this happens remove the remaining liquid with a syringe only, no other way.

Now, another 50 grams from the first beaker is added to the oily solution as the temperature is slowly raised to 83 degrees, after reaching this temperature, maintain for a full half hour.
Allow this solution to cool to 60 degrees after this period, maintain this temperature for another half hour removing the acid solution, once again leaving the oily substance behind.

30 grams of sulphuric are added as the oily substance is gently heated to 80 degrees celsius.

Once temperature has been reached and maintained, add in the acid from the second beaker. Slowly raise the temperature from 80 to 104 and keep constant for 3 hours.

After this time, lower temperature to 100 and keep constant for half an hour.

Remove oil from acid and wash with boiling water.
As you wash and stir, the solution will solidify.

Once solidification has commenced, generously add in cold water to turn it into pellets, this must be then dried.

Once you've got the dried pellets, this is the last and most important part: add them into an empty, dry pan, heat over stove for an hour, over this period, pellets must be observed for any sublimation and liquidation, it must then be drained and the remainder of solid is dried and put into containers for combustion.

Household subsitutes:
Sulphuric acid- battery acid
Nitric acid- saltpeter
