Insert a hot glue stick into a hot glue gun, then plug the hot glue gun into an electrical outlet. Allow the hot glue gun heat up for 10 minutes.
When you are using a terrarium as the base for your craft project, you may want to attach lighting inside of the terrarium so that you can light up the creation you made. Although the glow from tea light candles is warm and beautiful, it can be difficult to hang actual tea light candles inside of a terrarium because the wax could damage your craft project. One solution is to hang up LED tea lights, which display the same glow as real tea lights but without the dripping wax.
Take the lid off of a terrarium, and place it onto a flat surface with the underside facing up.
Squeeze a pea-sized dollop of hot glue onto the bottom of an LED tea light candle.
Press the tea light candle onto the underside of the terrarium lid. Hold it in place for two minutes to allow the hot glue to cool and harden.
Repeat to glue as many LED tea light candles into the terrarium lid, allowing the glue to cool and harden for two minutes each time.
Turn the LED tea lights on, then place the lid back onto the terrarium.
