A few years back, a company named Guyot made a product called firefly a Nalgene bottle light. They have since stopped making it. I and my son have one as do a quite a few scouts in my troop. They looked really cool coming across a parade field at night in complete darkness. I thought what if you attached one to the end of a Tiki torch stick. I did this last summer for camp and it was a hit. The two OA leaders loved it, they used throughout camp for night events.
So given they cannot be gotten, I decided to make one.
Also you could make this into a camp / deck lamp if you just cover the base, another idea was to place foil in the bottle to deflect light.
Other items can be put in the bottle shrunken heads or alien action figures for Halloween. Yellow and red work well, try it out and have fun.
Bamboo Tiki Torch.
Nagline Bottle (Yellow Red and Blue seem best)
1/8 inch Jute Twine
Dot It light (http://www.homedepot.com/h_d1/N-5yc1v/R-100670776/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=dot+it+black&storeId=10051#.UPxgGB0708w) Home Depot Black ~$7
Clear plastic sheet can be any type you only need about 4x4 inches
2 inch Hole saw (drill bit)
Fist take Tiki torch apart, leave the bottom wire loop in place.
Step 1: Ruin the Nalgene Cap
Size up the lens of the Dot It, It is about 2 inches (mine is 2 inches, if it is not the same light type measure . Remove the tether from the Naglene bottle, drill out center of the cap to create a 2 inch hole for the light. Use a utility knife to clean the edges.
Step 2: Assemble the Light Source
Drink the water, or water the plants and move on to the next step.
Step 3: Attaching the Bottle to the Tiki Torch
Step 4: Putting It All Together.
Assemble the bottle and place it upside down in the Tiki torch Lace the ends attached to the neck of the bottle through and around the bottom wire loop to secure it. Now take the loop you tied tightly around the body of the bottle and loop it over the bottom of the bamboo stick and bring it up to the bottle pushing it over the bamboo slats the harder it is the better you light will be held. Move it to within about 2 inches of the top. If it is tight it will not move.
You now have a lighted walking stick or a ceremonial Torch.
Imagine the looks it got as this glowed coming across the field at night, I was stopped many times to show it off (one scoutmaster blatantly stated he would steal the idea).
Someone in my troop suggested spray painting the stick to make it look like Gandalf's magic staff. It may be possible to disfigure the bottle into another shape using a heat gun but I have not tried this.
