This is great for someone having a low budget party!
the stuff needed is:
Soda/Fanta, 0,5L bottle
dumbbells ca 5 kg
Step 1: Finding the shape
I made a drawing of the bottle first, to know how big the vase had to be.
Step 2: Cutting, cutting, cutting......
Remember to cut out two pieces that don't have a hole for the bottle, these will be the sides.
