Note: A soda can full of sand will not hold all doors open.
Let’s get started.
Step 1: Materials and Tools
-empty soda can
• can must have the mouth hole cover attached
-enough sand to fill the can
-hot glue to seal the can
-spray paint to paint the can
And a few tools:
-needle nose pliers to help seal the can
-funnel to put the sand in the can
-glue gun to use the hot glue
Step 2: Prepare the Can
Start by bending off your pull tab. I don't have pictures of this because it's so easy to do. Don't forget to pull off the piece of the pull tab that remains after bending it off; you can see in the picture that there is just a little circle left where the pull tab is.
Next, find your mouth hole cover inside your can. Get your pliers in there and try to grab the edge of it closest to where it is attached to the can. It might take a bit of wiggling, but you should be able to bend the mouth hole cover so it is entirely outside of the can without breaking it.
Step 3: Fill the Can
Set up your can on a stable surface with the funnel stuck in its mouth hole. Start pouring sand in a little bit at a time with your hands, a trowel, or a spoon. Anything works, really. No matter how slowly you go, sand will get stuck in your funnel, so you should take it out of the mouth hole and shake that sand into the can every once in a while.
Fill the can to a little bit below the mouth hole. Now you have to compress the sand inside the can so you can fit more in. Fitting more sand in makes the can heavier and makes it harder to dent, because the sand will reinforce the sides. Using one of your glue sticks or some other object, push the sand down into your can. One strategy I used was to fold up a little piece of a paper towel and push that down on top of the sand with the glue stick, then just leave it in there.
Repeat this process until you can't compress the sand any more, and the sand is right up to the mouth hole.
Step 4: Seal the Can
First, carefully push the mouth hole cover down into its place and blow extraneous sand off the top of the can. Make sure you don't blow any sand out of the can! Pull the mouth hole cover back up after you do this.
Next, coat the top of the sand with hot glue. Sand and hot glue don't mix well, so be prepared to break resistant strands of hot glue with your hands.
Quickly push the cover down on top of the sand, holding it firmly in place until the glue dries. While still holding the cover down, put some more glue on the seam between cover and can. Don't worry too much about being tidy with your glue, you can always fix it later.
Let the glue dry, then make it look a little better. Pull off the little strands that aren't holding anything together, etc. until it looks decent. However, keep in mind that you won't be able to see the glue much when the doorstop is on the floor and you're standing up.
Step 5: Paint the Can
I taped off the top and bottom of my can so it would retain its nice shiny aluminum parts, but wouldn't have a label showing on it. See my pictures for how I taped the can off.
Be careful when you paint. You don't want any drips, so do even, light coats and then let the paint dry for at least a few hours before you do another coat.
I did three coats, but I was being extra careful. Two coats of paint will be fine for covering up the label.
Sorry I don't have any pictures of the painting process.
Step 6: Final Touches and Conclusion
To remove the printed date on the bottom of the can, pour some rubbing alcohol on a tissue and rub it off.
Congratulations, you've just transformed an ordinary soda can into a doorstop.
Usage: Since I'm lazy, I'll usually just kick the can over onto its side when I want to close the door, and then I'll grab it by its rim with my big toe to put it upright again.
