Simple ideas

No more twist ties or rubber bands
.
This method is waterproof and air tight 
Seal Plastic Bags with Old Bottle Caps

.
Seal your plastic bags with old cut off bottle tops
.
Cut up a disposable water bottle and keep the neck and top as shown in the photo

.
Insert the plastic bag through the neck and screw the top to seal.
.
The bag is now made air-tight so that water will not leak
.
The effect is achieved by the top and screw cap
.
Zip top bags are great, but sometimes they do not meet your needs
. .
 Particularly if you are travelling and there are no shops around
 ..
                                      Or you just don't want to buy anything
.
                         Try this idea, it just might save you some frustration


And if you find that neat then how about this:

In places where there is no grid, houses can be dark. But a simple solution--a plastic bottle stuck in the roof--can light up a room.

bottle lightbulb
We have lightbulbs made from glowing metal filaments, fluorescent gas, and LED diodes. 
And now we have one made of water. 
There is also a virtually unlimited supply since the "bulb" is composed of nothing more than one-liter plastic bottle, water, and bleach. 
The simple technology can be installed in less than an hour, lasts for five years, and is equivalent to a 60-watt bulb.
It works simply: The water defracts the light, letting it spread throughout the house instead of focusing on one point. 
The bleach keeps the water clear and microbe-free.
Adapted by students from the Massachusetts Institute of Technology focused on "appropriate technologies," the solar bottle bulb is illuminating poor settlements across the Philippines, where the organization Isang Litrong Liwanag ("A Liter of Light") has already installed 10,000 of them.

 Clever ideas.
