Day 1 Day 2 Day3
The process of experimenting

Our first boat: It couldn’t float because… The secret potion didn’t work Balloons too big so it was pulling boat up, so
cap wasn’t in water To make it better we… Added a paddle (fought against secret potion,
if potion worked anyway)
Day 1

Modified boat two by… Adding paddle to front to work with potion
(if potion worked) Paddle kept hitting the bottom
Day 2

We made a whole different boat called the Speed Splash!
It works because… We have a balloon that deflates When balloon deflates the air pushes the
boat The water bottle shape helps the boat cut
through the water easily The chopsticks helps keep it balanced
Day 3
