A simple ramp that you can make out of, for instance, an Easter egg box. All you need is scissors, Sellotape and a box.
Step 1: Cut Out
Get your box and cut the sides as shown.
Step 2: Sides
Cut out the parts as shown on the bottom base. Repeat on other side.
Step 3: Sides Part Two
With the pieces you just cut out, make a base for the side of the ramp. I suggest cutting a third one to go into the middle for extra strength.
Step 4: Attaching the Sides
Tape them together like so to the base.
Step 5: Finishing
Fold the top half of the ramp over and tape to the base and side supports.
