Caution "problem solver"!

So I had a clogged pipe in the bathroom. As the tube is round the corner and I did not come with a 3m-pipe cleaning spiral around the corner and also the counter chemical not helped from the hardware store, I have resorted to the "bomb".
So the stuff pure and first I thought that too does not help was after half an hour rest in a box. but beware! If the stuff comes in contact with water, there is a violent reaction! So provide for protection and ventilation!
