Annoying sticky pads

The finished result is good, but trying to get the tabs off the sticky pads was almost impossible.

Lego Fish Tank Light Kit

The light kit is AMAZING and really adds to the aquarium. The fish tank is in my classroom and I call them my class pets but when I showed the students that it lit up it just about blew their minds. Definitely would buy kits from here again!!
