Foldable/Portable Superlight Doggy Water Bowl $0

This is a bowl designed for giving your dog water when you take them with you to the park, or to the trails. The opening of the bowl is narrower than the base, so the pressure of the water in the bowl holds the bowl upright. You can fold it up and put it into your pocket when you are not using it.

You could go buy a foldable (and prettier) portable dog water bowl for $10-$15 or you could make one in less than 30 minutes and do some recycling too.

Step 1: Materials and Tools

Picture of Materials and Tools
You need the following materials:
Flexible Plastic Sheet at least 28cm x 28cm
Aluminum foil
Piece of scrap wood

I am using some housewrap that I got from the throwaway pile at at local construction site. It feels like fabric; is light, watertight, and strong. It is used in the same way that Tyvek is. (I do not know if Tyvek would work for this project).

And the following tools:
Ruler
Scissors
Soldering Iron
Marker
Clamp

Step 3: Plastic Welding

Do this outside, unless you like toxic fumes.

1. Heat the soldering iron
2. Place aluminum foil over the area to be welded together.
3. Move the iron over the area where you wish to make your joint, melting the pieces together.

I use the clamp to hold my piece of scrap wood which is my welding surface.

Practice on some scrap pieces. Use the flat side of your soldering tip. Also fold the Foil in half in order to minimize the chance of fouling the soldering iron with melted plastic.

That is the basic technique. Now we start by tacking corners.

Wow, that is pretty neat. I am surprised. Thanks a bunch for letting me know.

Yeah. I was excited to see instructables in the press again. I bet you get a whole bunch of traffic to this instructable now. Newsweek has loads of readers.

You know I never expected this instructable to get any attention. This is neat. +1 for recycling/dumpster diving.
This is so cool!!!

Nice work. Also, this has more potential uses than watering dogs. L

Thanks for the feedback guys. The bowl is holding up well. The dog loves it. @ Graham, thanks for the baking sheet tip. Don't have any now though.
Nice project. Silicon baking sheet is also good for forming welds through and it never sticks.

This is a 'classic' project, and makes a great instructable! You can actually boil water in a paper bowl similar to this...
