The second finalist in our DIY Eco-tech contest is a solar-powered bubble machine sent in by reader Rob Matthies. Rob equipt a store bought bubble machine with solar panels to enable it to work whereever there is sun (and Rob says even on some overcast days as well). Althoughly mostly for children, Rob has seen many adults also have their interest piqued at his bubble machine. The machine has seen time at events throughout the city of Vancouver as Rob has been able to help bring awareness of solar energy throughout the notoriously rainy city. Thanks Rob for entering our contest.
