KC-135A model tankers and some B-52 models used water injection to increase
thrust from the engines during takeoff, they carried enough water to burn
120 seconds. I can tell you from experience that the gained thrust would
put you back into the seat for sure. The exhaust was pitch black .. Walnut
shells are used in some A/C engines to clean the combustion sections of the
jet engine, but not in flight.. ;)
