A hot glue gun can solve so many of your problems, but there's no doubt about the fact that this tool does have one downside; it's powered by electricity. And while this isn't really an issue when you're at home and have full power, there may be an instance where you desperately need glue during a power cut or an emergency situation. But there is a way to get around this problem.
By dolloping some glue on some matches, you can ensure that you have some glue handy during a power cut. Simply use a candle or another match to melt it once again.
