During the trial of the conspirators , the prosecution stated that each bomber would board a plane with the " necessary ingredients and equipment " . They would then construct the devices mid-flight and detonate them . The hydrogen peroxide would be placed in 500 ml plastic bottles of the Oasis and Lucozade soft drinks . A sugary drink powder , Tang , would be mixed with the hydrogen peroxide to colour it to resemble a normal soft drink . Hydrogen peroxide is widely available for use as hair bleach and along with the other ingredients can become explosive if mixed to a specific strength . The mixture would be injected into the bottles with a syringe . The bottle 's cap would not have been removed and the hole would have been resealed , thereby allowing the device to resemble a normal , unopened drink bottle when screened by airport security . The use of liquid explosives with dissolved powder is similar to the composition used in the 21 July 2005 London bombings , using hydrogen peroxide and chapatti flour , activated by a detonator
