Mae pawb ond yr hanner-siarc wedi gadael yr ardd yn ystod y llifogydd o gwstard cariad Santes Dwynwen. Maen nhw’n aros mas tu fas ar y stryd.

Mae’r hanner-siarc yn parhau i ymarfer nofio yn lle jyglo.

Ond mae rhywbeth od yn digwydd.

Wrth i’r hanner-siarc geisio mynd yn gyflymach, mewn gwirionedd, mae mwy o wrthiant yn y cwstard. Ar ôl sbel, mae e’n mynd yn styc.

Hylif an-Newtonaidd yw cwstard cariad Santes Dwynwen, mae’n debyg.

Stuck

Everyone apart from the half-shark has left the garden during the flood of Saint Dwynwen’s love custard. They are waiting outside on the street.

The half-shark is continuing to practice swimming instead of juggling.

But something odd is happening.

As the half-shark tries to go faster, in fact, there is more resistance in the custard. After a while, he gets stuck.

Saint Dwynwen’s love custard is a non-Newtonian fluid, apparently.
