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?

I think that there will be a Dramatic change in the water, because of the washing liquid.
Like this:

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

We gently put our boats on the water, and tapped the water with washing liquid on our finger.

Observation (What happened)
Exactly what I predicted.

Conclusion (Why I think it happened)
The washing liquid must of broken the surface tension, causing the boat to go ZOOM

Thanks for reading!
