What an interesting day!
Any day when four students are charged with offences under the Explosives Act has got to be action packed. Going home in the middle of the day to have a shower - that's fun too. Dropping a bottle (that a student has passed to you) because it is bulging, bubbling and getting warm is always a real highlight. Having an explosion that is so loud it could be heard in the staff room (150m and two buildings away) occur before the bottle hits the ground next to your foot is an absolute blast! And learning how easy it is for kids to make a chlorine bomb - that's always interesting. Fortunately I wasn't hurt, and neither was anyone else.
