We use a lot of electronic devices that use batteries. Sometimes the batteries can be recharged, but often not.
Of course, we return the non-rechargeable batteries neatly to a collection point, but...... they are often not completely empty yet! They may contain too little energy for the device they come from, but the energy has not yet run out. With the "Squeezer" you can get the last bit of energy out of the battery (squeeze!) before the battery disappears into the recycling bin.
So what does the "Squeezer" do with this last bit of energy? The "Squeezer" uses the energy to light up a bright LED, so it's a flashlight!
You can choose between white light or red light. This can be useful as a marking in the dark, for example when you walk along a dark road. White light on the front, red light on the back.
But the red light is also useful when you go stargazing, for example. Astronomers like to use red light when they are working outside. In the dark your eyes are used to low light, when you turn on a white flashlight, your eyes have to get used to bright light again, after this it takes a long time for your eyes to get used to the dark. With red light, this is much easier!
The "Squeezer" also has a push button with which you can use it to give light signals. This way you can communicate with light-Morse signals!
AA and AAA batteries fit in the "Squeezer", these are the most commonly used batteries nowadays. For Scouts who want to experiment, the "Squeezer" also has two special connectors. Other energy sources can be connected to this. Think, for example, of a 4.5 Volt battery or a 9 Volt battery, or use solar cells and supercapacitors. You will have to tinker with some wires.
If you are a real researcher, you can also use these connections to connect your homemade battery. You can make your own battery with, for example, a lemon or a glass of cola and a galvanized nail and a piece of copper wire. Will you be able to generate enough energy for the "Squeezer"?
Finally, two important instructions for use:
1. Do not use rechargeable batteries in the "Squeezer"! Rechargeable batteries cannot withstand it when they are completely discharged (all energy out). This will break down the batteries and prevent them from being charged (properly). So only use the "Squeezer" with alkaline (disposable) batteries.
2. If you don't have an "empty" battery, you can of course also use a new battery. Then you can enjoy your "Squeezer" even longer!
With the "Squeezer" you are energy-efficient, green and Future-proof as a Scout!
