Easiest Concrete Casting Ever!

1 Hour

Use your empty cans and make the coolest concrete vessels. Cost = pennies and no fancy mold... You will have your friends saying 'what the'?! (btw, be patient; apparently I am crashing the servers on my site)

Go into your recycle bin and collect those soda and beer cans. Force out the bottom of the can with the end of a broom (easier removal later...) after cutting off the top. (full tutorial here) Make some dents and wrinkles in the can.

Quick-setting concrete mix is used here. I use RapidSet Cementall. Mix up a small quantity and be aware you need to work quickly since it sets i minutes. It should be of an easy flowing consistency.

Pour into the can and turn to coat all the sides. Continue turning to keep from settling on the bottom. It sets in minutes, be patient. Any extra can be poured into next can.

After few minutes it will 'stay put' and you can let it cure for about 1 hour. If the concrete is really thin repeat and pour another layer for reinforcement.

Once it is thicker (3mm or so) and it has cured, you can remove the can. Use caution as it is sharp. I like to use tools and rip the sides down in strips. The bottom is slightly more difficult to remove, so pulling strips work best.

TADA! The finish is super shiny and quite interesting. You can now add colour of preferred or enjoy as is. You can't get an easier mold than this. I LOVE concrete and have a lot of unique projects

Metallic paint seems so appropriate... So cool for so little effort!

      I tried at first without and it was next to impossible to pull out that part. I'm pretty sure it is formed in such a way that it is very strong and keeps it's shape. Bumping it out makes removal easier.
