Well I just wanted to know what people are using for cap in bottle tricks- get some views on the products out there. If I was to be more specific with regards to myself I would say something that is impromptu, using either a borrowed bottle or cap. I'm a student and I normally do my tricks in the student bar or during/inbetween lectures/seminars where I would normally have a plastic water bottle or coke bottle on me, so that it doesn't look odd me carrying a glass bottle around. I'm also head of fundraising/charity work/volunteering at the uni, so I normally do tricks when we are doing street collections, charity stalls etc where I sometimes carry a water bottle to drink from.
