When we travelled to Barcelona last year I spent an age watching these bubbles being made by a street entertainer in Parc Guell. I was reminded of these giant bubbles when my daughter came back from a party yesterday with some bubbles with quite a large wand.
It was basically two rods with a laces wrapped around them - I'm sure his were probably properly secured which ours were not but then I was having to try and work at the children's speed of I want to do it now! Anyway they both found some broken garden canes and we rummaged in the shoe polish box and found a couple of old laces. The washing up bowl and a lot of washing up liquid was commandeered and a watering can full of water to help get the mixture just right.
