'Gabriella!' Troy cried as he hurried into the almost-empty science classroom.
'Oh, hi Troy,' Gabriella smiled. 'Just a second.'
'No, this can't wait a second,' Troy argued. 'We're late for singing practise!'
Gabriella looked at him, her eyes magnified by the safety goggles she wore. 'Oh no, really?' she gasped. 'I was so busy with my experiment…'
'Can you pack it away quickly?' Troy begged. 'Darbus is going to kill us if we miss practise again.'
Gabriella shook her head. 'I'm sorry Troy,' she said 'but once set up you have to finish.'
'Well isn't this a sight?'
Troy and Gabriella turned to see Sharpay leaning against the doorway. Ryan was behind her.
'By the way,' Sharpay added 'Darbus told us that if you missed two more practises, she's kicking you off, no matter how good you are.'
'Well, that's just great,' Troy muttered.
'See you later then,' Sharpay smirked, walking past them to the other door out of the classroom. Ryan followed her, but 'accidentally' tripped over Troy's leg and stumbled into Gabriella's stool, causing her to empty an entire flask of some sort of chemical into the beaker. The beaker began to boil and spill over the edge.
Then the beaker and the mixture inside the beaker exploded. The mixture hit Gabriella, Troy, Ryan and Sharpay. They fell to the floor, unconscious.
