Race a speedboat

Race a Speedboat
Can you make a paper boat race across the water just by gently touching the surface of the water?
Hypothesis (What I think will happen)
When we touch the water the dishwashing liquid will make bubbles from the dishwashing liquid and will pop and make the boat move.

Coloured card, washing up liquid, pencil or sharpie, scissors, large container of water.

Method (What we did)
We placed a boat we had made from just coloured paper. Then we put our finger in the water with the dishwashing Liquid and it starts to go to the other side of the container.

Observation (What happened)
We placed the boat on the water, then we placed our finger in the dishwashing liquid and the boat went to the of side of the container.

Conclusion (Why I think it happened)
The dishwashing liquid makes a force between the Paper pushing it away.
Go on move!

Short Experiment to Follow Up
Make Metal Float
Gently place a paperclip on the water’s surface.

Hypothesis (What I think will happen)
just like a boat it will making some water go around it

Observation (What happened)
Someone gently placed the paperclip in the water making like a dint in the water.  

Conclusion (Why I think it happened)
I think an air bubble forms in the middle of the the paperclip but it sinks a little bit.
Yes the paperclips floating


  1. Wow Cameron,
    Your science experiment looks great.
    I like your captions.
    I like your description too.
    Well done.

  2. Nice work Cam I like the way how you did it nice and clearly for the reader.
    Keep up the amazing work and don't stop.
