2 boys, bar of soap, and a bowl of water

Equals BUBBLES

Evidently Kurtis has figured out how to blow bubbles with his fingers.

See how big he can make them

So he taught Sam how and he was trying so hard.

And finally....SUCCESS

So this is why it takes my boys forever in the shower and the soap is a pile of mush.
They all confessed to blowing bubbles while in the shower.
