Bri is dressed in her chequered skirt, white shirt and a tie with long black socks and her Calvin Klein trainers and lou is dressed in her long dark blue st trininas school uniform with long white socks and white converse.

Unfortunately for these two girls, after not seeing eye to eye they have been partnered up by there science teacher to do an experiment on some sort of slime (gunge) The science teacher tell the girls he needs to go get the test tubes and has told the girls to be seated and to not touch anything Shortly after leaving the class room bri and Lou start to investigate what is in the bowls picking them up smelling them and dipping their fingers in the very bowls they was told to leave alone. Both laughing and being mischievous bri wipes her finger on Lou's leg leaving a trail of slime. Bri then dips her finger in another bowl accidentally spilling it over the floor and after panicking and Cupping her hands to put it back in the bowl and trying to come up with a story to what happened it starts to take a turn for the worst. Bri wipes here hands over Lou's long white socks and begins to try frame Lou.

Very quickly it becomes tit for tat and bri and Lou keep putting different colours of gunge over each other planning to blame one another. Bri then takes it to the next level by pouring the bowl over Lou's head covering her in the slime and of course that only leads to Lou reacting and doing the same. Before they know it all the bowls are empty and both girls are completely covered in bright colourful gunge. Sir then comes back and is shocked and very angry with the girls as they try to blame it on each other they are then sent to the principals office.
