Inside This Book

Harold Has Plenty of Time... Or Does He?

It's the night before the big Science Fair at Bondi Primary School, and Harold has a teensy tiny problem: he hasn't started his project yet. Not even a little bit.

But Harold's not worried! He's the king of last-minute ideas. He'll just whip up something quick and easy. How hard can a volcano be?

Spoiler alert: VERY HARD when you use the wrong ingredients.

When Harold swaps baking soda for baking powder and creates the MEGA 3000—the most catastrophically erupting volcano in science fair history—he learns that procrastination and shortcuts lead to spectacular disasters. And pink foam. SO MUCH pink foam.

Join Harold on his first hilarious misadventure, where a simple mistake turns the gym into a slip-sliding foam party and teaches one tall, clumsy kid that planning ahead isn't just boring grown-up advice—it's actually, pretty important
