Actually, after much pleading and persuading and me finally remembering, bear has a packet of balloons. Balloons have been blown up, released, blown up, released, squeaked, rubbed and bounced. I think I shall start keeping a stock in - balloons aren't very durable here.
Mind you, the bright idea he had about filling the balloon in the sink and then pouring it out in the bath was not a success. I am testing out the fifteen minute wash cycle on the new washing machine with the soaked towel, cloth and bath mat.
Of all the things he could be happening to, a soaked bathroom floor isn't the worst. There are two crystal growing kits in bear's Christmas/birthday present pile. I think I'll have more to worry about with them.
