This is the instructable for making the colouring trash picker, used in the corresponding instructable "Create colourful wastelands by colouring waste". https://www.instructables.com/id/Create_colourful_wastelands_by_colouring_waste/
The colouring trash picker is a tool with which you can clean the streets and at the same time colour them! The graffiti can attached to the trash picker, will spray paint by pinching the handle of the trash picker which you also use for grabbing the trash.
In the list below you find everything you need for making this tool. It is possible your trash picker does not work exactly the same as used for this construction. In that case maybe some adjustments are necessary to make it work.

- Metal tube ?0,65 inch (16,5 mm) inside
- Metal stiff wire ?0,079 inch (2 mm), length depends on length trash picker
- Screwdriver or wrench

Step 1: Get Yourself a Trash Picker and Graffiti Can
Get yourself a trash picker, or also called a helping hand. You might find them in shops fore healthcare, or cleaning companys. In the image below, you see the trash picker that was used here.
Just like this trash picker, most of them work with a cable walking through the pole.
By grabbing the handle, an axle moves to the back on witch the cable is connected. On the other end (the bottom end) the cable is attached to the grabber, which closes due the pulling movement of the cable.
You also need one graffiti can already, for being able to adjust the construction to the right can size and making sure youre construction works!
Step 2: Attach the Clamps for Mounting the Graffiti Can
You can mount and disassemble the graffiti can on the trash picker very easy by using two hose clamps. Open the small hose clamp completely and pull it through the large clamp. Now you mount it on the bottom end of the pole so it grips the large clamp to the pole. Mount it at the left side on a distance of 9 inch (230 mm) from the bottom end of the grabber. When you are left-handed you should mount the large clamp at the right side.
You open and close the hose clamps with a screwdriver or a wrench.
Step 3: Make the Metal Strip That Will Push the Graffiti Can
Saw a metal strip of approximately 0,8 inch (20 mm) wide and 9,8 inch (250 mm) long. Bow the last end of the strip on 35?. On this end, you weld a metal tube that will fall over the head of the graffiti can. The inside diameter of the tube must be the same size of the head of the graffiti can, this is ?0,65 inch (16,5 mm). Saw this metal tube so it will be 0,5 inch (13 mm) high. Drill a small hole in this tube, this is were the paint will be sprayed through. Drill a hole of approximately 0,275 inch (7 mm) on the other end of the strip. We will use this hole to attach a metal stiff wire to the strip.
Step 4: Drill a Hole Above the Superior Clamps
On a distance of 3 inch (75 mm) above the place where the clamps are mounted, you need an axle as a rotation point for the metal strip that is going to push the head of the graffiti can. On this distance, drill a hole where the bolt M4 will fit through. Make sure there is little margin. Attach the bolt, washer and the spacer on the pole. The spacer must be at the left side of the pole.
Step 5: Mount the Graffiti Can
Mount the graffiti can in the hose clamp the way you see in the picture.
Step 6: Weld the Spacer to the Metal Strip
Put the tube with the metal strip over the head of the graffiti can and let the strip rest on the spacer. Draw a line where the metal strip and spacer touch each other and disassemble the spacer. Weld the spacer on the strip where you just drew the line.
Now assemble the spacer again, being attached to the metal strip.
(the construction in the picture is not exactly the same as described above, but it works the same. Here was used a long threaded rod, a nut, and a spacer without thread. The threaded rod is welded on the metal strip)
Step 7: Attach the Metal Cable to the Trash Picker
Get a straight metal stiff wire of about ?0,079 inch (2 mm) and long enough to reach the distance from the hole in the upper end of the metal strip, to the axle in the handle where also the original stiff wire (that leads to the grabber) is connected. Bow one end of the wire round and hook it on the axle in the handle. Pull the other end of the wire trough the hole in the metal strip, make sure it is tensed and also bow this end of the wire round. Cut the wire on the right length after you bowed it.
Step 8: Try It Out!
Now try it out. If it works youre finished of course! But it is possible things do not go as smooth as you would like. Try and adjust some distances then, and see if it works better.
