How To Make a Secret Hollow Soda Can:

For this you will need:

  • Coke cans/soft drink cans/beer cans whatever you can find or want to use (these cans must be unopened)

  • Sharp scalpel or knife

  • Can opener

  • 1 bag of plaster of paris

  • 1 small glass jar with metal screw on lid (small spring valley bottles or those small jam bottles are good)

  • cup or jug

  • glue gun or strong super glue

Ok, now you have your materials, grab your unopened drink can and sharp knife/anything pointy and sharp.
Then on the bottom of the can make a small hole to drain the liquid out of the can (pic 1) into a cup or jug, this can be messy so start off with a small hole and slowly make it bigger. Once the can is empty we get to the tricky bit, I have ended up having to restart after this step.

Now to remove the top of the can. It’s actually not that hard once you know what you doing. Grab the can opener and grip it on the top of the can, making sure that the can opener is cutting the can part and not the top ’lid’ part. Some can openers won't allow you to cut like mine, but most will be able to do it properly.

Once you have cut this lid off, clean it up and wash the can out thoroughly. The lid may contain a few little dags of metal so remove those if necessary. Now, you should be left with an empty can and a lid that fits on the top flush.

Now, take the glass jar and remove the screwtop lid. Take the top of the can and glue the jar lid to the bottom. Wait until it dries and screw it on the jar to test to see if it strong enough.

Now to fill the can with the plaster. Mix it up in a bowl and you will only need enough to fill the can about half way. Then use a small bit of silicone or glue and patch up the hole we made in the bottom of the can, you don’t want any plaster leaking.

Take the top of the can with the lid glued to it and we screw it onto the jar. we then start to pour our plaster into the can filling it to about halfway. Once at half way, we take the jar and lid and place it in the can. This is to get the jar at the right height so it closes and looks like a normal can. If there is not enough plaster in the can, fill to the desired height and leave the lid on the can until the plaster has dried. We want the plaster to create a base for the jar but also hold it firmly inside the can. The plaster should cover at least half of the jar.

After few hours, check to see if the plaster has dried. If it has, slowly unscrew the lid off the top of the can to test to see if the jar has held. Test screwing the lid on and off a few times just to see if everything is held and that is pretty much it.

You can modify the can and make it a bit more stealthy, and that is to add a water (or any other type of liquid) pack to the bottom of the can and plaster over it. This creates a liquid sound inside the can when it is shaken, so it even sounds real.
