The Answer Lies in the Water
Some people may view leaving their keys inside their tent as a straightforward solution. Still, for others, particularly those who drive their own vehicles, it can be a source of significant anxiety. The solution to this problem is as follows. Don’t throw away the cork from that empty wine bottle just yet because you can still make use of it in some way.
The only thing you will need for this activity is a cork. It is not important what kind of cork is used to retrieve keys from the water as long as they are retrieved using one. When you are in water that is not very deep, you should fasten your keys to something that is relatively heavy so that they will sink to the bottom rather than float away.
