Name of experiment: home made water bomb
Group names: Zeke,Justice,Wharengaro ,Jordan,Traezarn.
Change question: How is the bomb going to blow up?
Prediction:The paper will get soggy and break.
Observations:
We saw…. The water splatter everywhere on the ground when we threw it at the ground. It had water inside and when it hit the ground, it unfolded and the water escaped. It blew up by force and it collapsed. It did not get soggy and break. We tried different ways.

Conclusion/ Answer to your question : we were not right in our prediction. The paper did not have time to get soggy. It was the force that made the water escape.
Extending the learning
I wonder questions (Trying new things):I wonder what would happen if I folded it inwards.
Comparing Original (Experiment with trying my new ideas):
We tried folding it in and it didn’t work because it stayed in one piece when it hit the ground.

What is happening inside the water bomb to make it collapse? Justice thinks it is pressure.

What would cause more pressure so a big
Jordan wonders…. Would the explosion be bigger if we use vinegar and baking soda and some sellotape to block the hole and shake it?
