The fireworks for tonight's display have been set up on the three barges out there in the middle of the harbour.Now the budget for this event is a staggering 3 quarters of a million poundsand it takes months of planning and preparation.To find out a little bit more, I went to meet the brains behind the display, Wilson Mau.Beautiful early morning in Hong Kong and I am heading out to the barge,which is where Wilson and his crew are working, setting up all the fireworks in preparation for the display.It takes a week to load up the barges with 4.5 thousand kilograms of highly explosive pyrotechnics.Wilson has mapped out a spectacular show,so he's making sure they are positioned perfectly to go off at the right place and time.So those are the launch tubes. The actual explosives, the fireworks are stuffed in those?Yes. Right. There is an electric match, together with the shell.When the electric match ignites, the shell is going to propel from the launch tube.Is there any danger when you've got this much explosive
