I used to create mini submarines and place them inside clear glass bottles with water to make them float. Adding some weight carefully to achieve balanced buoyancy to make it stay at the middle is a challenge. To my surprise, to calibrate its buoyancy inside the bottle, I just twist the bottle cap tighter then it sunk slowly, and slacking the bottle cap twist makes it float, so i used the cap to float or sink the object accordingly. What is the real principle for this? I'm wondering of relative density or pressure makes it sink or float accordingly.

Can you help? I'm just about to start a new job at an estate agent and have a few concerns regarding personal safety one of which being that my car does not have central locking. I would like remote central locking and was wondering if it would be worth my time (and money) getting it fitted to my current car (if this can be done) or whether I should just buy a car that already has it? The problem I have with buying a new car is that I have only had my license for a couple of months so my insurance will be quite high. What would you suggest? Thanks for reading xx

me and my wife have a great marriage except for the sex part. we have been married for 7 years. she wants me to go see a sex therapist. what is the difference? and can they really help? it has started to affect me outside of sex though. like self confidence, and it has now consumed my life. the problems we are havin are normal for 18-20 year olds. i should have outgrown them. now that problem is leading to problems i shouldn't have till i am like 80. i have tried everything i have ever researched. a therapist is all that is left. i feel like such a loser asking this question on here like this. this probably isn't the best place to ask a question like this. i don't know. :(

... For a romantic break. After chopping some wood, the man says "My hands are freezing" she says "Put them between my thighs to warm up"
After lunch he chops more wood and says "My hands are really freezing" so she says "Put them between my thighs and warm them up again"
After dinner he chops more wood and then says "My hands are really, really freezing" and then she yells "For F*^*$ sake! Don't your ears ever get cold...!!?"
