Oz had sent an email to the class telling them wear clothes that could stand up to some rough handling. As each student entered the Danger Shop, he handed them either a squirt gun or a bucket of brightly coloured water balloons.

Once the entire class had arrived, he began. "Sometimes you need to know how to make the most of what you've got," Oz told them. "You might be in competition with people who have different resources to you, they may be better resources, they may not. But usually? Knowing how to effectively use the resources you have can make all the difference."

"Other times, you just need to know when to cool off." Which would be when he triggered the catapult full of balloons aimed right at the class.

[Done!]
