Bioplastic balloon

by Luke

 

Hi there! My friends and I (we are all 10 or nearly 10 years old) have been working on a bioplastic balloon made from the agar/starch blend recipe. We have successfully made a plastic light and flexible enough to float, but we are having troubles sealing the two halves of the balloon together. We are currently using an impulse sealer, but the seals come apart easily. Does anyone know of any eco-friendly way to seal bioplastics together?
