Race a speed boat

Race a Speedboat

Can you make a paper boat race across the water just by gently touching the surface of the water?

Hypothesis I think the dish washing liquid will make bubbles  and the the bubble will make wave and the boat will move.

Materials

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

Method Cut a piece of paper into any shape and put it into a container and fill it with water put the paper in the container and then put a drop of dish washing liquid and slowly put your finger on the water behind the

boat what will happen.

Observation We put our boat on the water and the dish washing liquid and it was like the boat had an allergic reaction to is because it zoomed away up the water and the force of air made it float.

Conclusion I think that the boat zoomed off was because the dish washing liquid was forcing the boat to move.

Short Experiment to Follow Up

Make Metal Float

Gently place a paperclip on the water’s surface.

Hypothesis I think the paper clip will float because there air is pushing it up.  

Observation When you slowly put the paper clip in it floats it is because the air is holding it up but when you look at it clearly it is almost like there was a dip in the water from where the paper clip.

Conclusion

This one is the paper clip one.

It was so light that it made the water hold it up but when you look it up closely it had a dip in the water it was really cool.  

This is the one the paper boats.
