IT IS SUUUUUUPER EASY
Step 1: GET AN EMPTY ALTOIDS TIN
Alright, we all got these somewhere around. Get one of these and some duct tape. I used red black and white duct tape. I also used a red sharpie to write in first aid.
Step 3: LAYER TAPE
Okay, so right here all I did was take of the lid, and put a piece of black duct tape on top of the words so it wouldn't be seen through the red duct tape. After that i bent in the side hinges of the tin.
Step 4: DUCT TAPE IT ALL
Use the red duct tape to cover all of it. I covered it all because when I close it the extra duct tape where it closes will create a super strong seal.
Step 5: DUCT TAPE THE BOTTOM PART
After that, I duct tape the bottom, and cut out some small thin strips of duct tape to use as handles and taped them to the side, as seen in the pictures.
