Burning champagne cups
You need to buy two nice champagne cups, two gel-like wax-wicks and gel-like wax. The gel-like wax can be bought in every arts and crafts supply store.
The wax-wicks have to be positioned upright in the middle of the champagne cups. To achieve that position, the wick has to be put between two little sticks of wood. The gel-like wax can be bought in various colours which can be mixed with each other. Nevertheless, I would recommend the clear one. You have to fill in the wax layer after layer to prevent the coins from sinking down to the bottom. This action has to be repeated as many times as necessary to secure the coins are where you want them to be. The money can be even nicer and shinier when it has been previously cleaned with a commercial ultrasonic. I do not recommend to fill up the last third or quarter with wax because then the glass looks nicer when it is burning.
After you have finished your champagne cups, fix them to a silver plate and decorate them with bows. It is best to present two more champagne cups with real sparkling wine.
Have a nice time preparing this money gift and presenting it on the wedding celebration!
