If you have a need to water a plant that is higher than you can reach, you don't have to go and get the step ladder with this little device
Step 1: Supplies
One spray bottle (Dollar Tree: $1 - or recycle something)
some aquarium tubing
long branch or bamboo stick
3 small sections of heat shrink tubing one each of 3/4", 1/2", 1/4"
female to male hose adapter from the hardware store: 5/16" female to 1/4" male - $2-$4
Step 2: Remove the cap
Unscrew the nozzle cap from the bottle
Step 3: Attach 3/4" heat shrink tubing
Slide the nozzle cap into a one inch section of 3/4" heat shrink tubing and then use your heat gun to shrink it down around the cap.
Step 4: Attach the 1/2" heat shrink tubing
Now, slide an inch section of the 1/2" heat shrink tubing over the previous section of tubing.
Step 5: Attach the 1/4" heat shrink
Slide a small slice of 1/4" heat shrink tubing onto the tube and gently slide it up over the previously shrunk tubing section. It will be a tight squeeze, but just be gentle and twist it a little and it should slide on.
Use the heat gun to shrink this piece down around the aquarium tubing.
Step 6: Attach a long stick
Tie the end of the aquarium tubing to the end of a long branch or stick. Use a rubber band or cable tie - whatever you think. The rubber band I used is not aesthetically pleasing, but it works. Heat shrink might be a better choice here.
Step 7: Test it out
When you squeeze the trigger, the water should flow through the tube without leaking.
Step 8: Now you can reach very high plants
Step 9: Another option
I also found these little adapters at the hardware store which perfectly fit my Dollar Tree sprayer bottle - aquarium tube combo.
The adapter shown is a 5/16" female to 1/4" male coupler. About $2.75
