Treasure Box Toys (How To Make Treasure Container). Metal detection in water zones like rivers and lakes can be tricky. Because you do not want to find coins and such like only to lose them to the current; talk about going with the flow.
- Even the container you choose needs to be proper. Otherwise, when sealed, the air inside does what physics commands. If they are in the water or fall in, they will be carried away along with whatever you treasured up in the past hour or more.
- You are going to learn how to make the best kind of container for these tasks. They do not come readymade nor are they sold in stores.
- Get yourself a medium-sized plastic jar. Yes, you read it right, go get one (peanut butter springs to mind).
- You are going to put some holes in it but not just anywhere. You can guess why we need holes, so when you are in the water metal detecting, air inside the sealed jar will not cause any float-away problems. Water can enter and weigh the bottle and its contents down.
When you leave the water, it should drain out of the bottle; whether you have the bottle on you or in a bag slung around your shoulder, the bottle’s weight can make things uneasy, hence the proper hole-making idea. Do not jab holes in it. The weight of metal objects or coins can place pressure on those regions and cause a linear tear along the plastic bottle. For integrity, use a drill.
Drill 4-5 holes around the jar’s circumference, an inch or so from the base. Repeat another series of holes an inch above this, and then one more series nearer the top; not close to the lid, mind. This way, water gets in quick and exits just as fast. Rough edges around each hole is yet another issue, so smooth it out however you can otherwise it is best you head to a welder and have them burn holes in the bottle. The idea is to have a container that you can use for the long-term; none of this is overkill.
- You can use a home welder, if you have one, heat the tip of a long Phillips-head screwdriver, and poke holes as needed.
- This process burns a hole so neat that it has no rough and ragged edges. Smoothness is the way to go; optimal jar integrity.
- The holes, remember, should be neither too small (or water will not quickly go in and out) nor too big (cut silver and smaller objects could fall out).
- The last thing you want is to lose the jar, lid, or both. Here is how not to… Heat the screwdriver head once more; make a hole in the lid (at the center) and one in the bottom (along that same central axis). Drilling is inferior to melting and prevents cracking.
- Get a nice slim cord or line. Tie one end of it. Thread the open untied end through the bottom hole and fish it out through the lid. Put the lid back and cinch the line. Tie a loop at the free end; do not cut off any slack. Tape the knots for increased integrity.
You now have a treasure container jar that can never get lost while also being quite sturdy. The lid can be moved along the thread and screwed back in place after you add some more metallic discoveries; lid will not float away thanks to the top loop.
Snap the lid to the bag using the loop at the top end. Water and floating away are no longer burdens for the jar itself. This jar is ideal even for diving purposes.
