I saw Jorge Garcia from the show "Lost" on a talk show last year and he was wearing a fish bowl costume using a shower curtain. I then used my skills as a former Pre-K teacher and added my touch to make this Homemade Fish Aquarium Costume.
I got the box from the lost 'n found from our local library. There was of course a opening for all the stuff that was in it. I cut out two side windows and placed clear wrap on them. I put a blue tablecloth to cover the box and cut the windows out and used black tape to trim it. I glued all the aquarium extras to the box. I placed a turtle, clown fish, starfish also in the box. I used fishing line and taped the fish "cat" toys up.
I found a fish mask online and colored it and used a strap from swimming goggles to finish the mask. I also added a light at the front top to add the glow of an aquarium and for his safety while trick or treating.
My 5yr old couldn't make up her mind for Halloween so we got online and did a search. When we got to this site we saw all kinds of stuff and she couldn't get over some of the fish tanks so I suggested making the Dentist's tank from Nemo. She loved it and this was born...
Since we used a box, I had to copy the inside to the outside and it was just as good as glass. I also did a paper mache candy bucket made to look like a fish food container. This homemade aquarium costume idea won best homemade costume at the local fair and I don't think I can ever top it!
