Alright here is a great April Fools Day prank for those of us with over protective mothers.
Here is what you will need;
1 Lid from a tuna can
a red sharpie
clear drying glue
This project is extreme because of the extreme worry and anger that your mom will experience when you use this in front of her.
CAUTION: This instructable involves thin sharp peices of metal. I am in no way responsible for injury that may accure while building or using this.
Step 1: Measure
Take your red sharpie and mark the width of your finger on the edge of your lid.
Step 2: Cut
Use your tin snips and cut on the inside of each of your lines, about half an inch in.
Step 3: Fold
Fold the flap toward the center and crimpin place(you can use pliers if you want to).
Step 4: Glue
Take your glue and apply it on the inside of your cut. This is very important because it is what prevents your hand from being cut open, so apply liberally and allow it to dry.
Step 5: Try It On
Slip it on your finger and see how it looks. Take some red aint and apply it around the your finger so it looks real. (you can make the paint look more like blood if you want i used i had) Enjoy!!!
