This is one of my rock structures, there is no glue or adhesive, just gravity and friction.

I used acrylic paint to create green lightning on the sides of the helmet. This was my first-time using this medium so I'm happy it didn't turn out worse.

This tree was created using 250 kcmil electrical wire. This is serious wire, capable of carrying 290 amps! I used a one foot section and twisted it by hand.
