4 AWESOME INVENTIONS 

Can you tell me which type of pin you are using to make soldering iron

Many people are showing the use of short circuits to make soldering irons or heating elements. The battery might explode. You need to read the signs on the battery. Better to use an expensive power supply with short circuit protection and current limiting. However, using a simple mains power supply would be even worse than the battery.

Using a battery for an aquarium is a good idea because a mains power supply can short with the water if the device falls in.
