Any problems to the bottle? Im gonna leave a little bit out for room to expand.Im thinking since the sugar acts as an anti freeze it would expand but do nothing to the bottle since the ice particles wouldnt stick together.
use woodcut the angles and use tack nails and wood glue to adhear them togetherdecorate when fully dry
try using regular plastic pipe its cheap! and not as heavy as wood will beyou can have your dad help you find one in the length you need at the hardware store, and it could be a project you could work on togetherHow fun is that! A great craft to do with your dad.
It will burstThe bottle will contract, but the ice will expand in all directions, widthways as well as into the room you leaveI have seen frozen aluminium beer cans - messy!
