Take an empty plastic bottle

Remove the bottom of the bottle by cutting it with a pair of scissors.

Take two drinking straws. Tie them to each other. Tie one balloon to the end of each straw. You’ll also need a rubber glove or any other plastic sheet.

Insert the prepared straw and balloons set into the bottle from the cut end. Use cotton wool at the mouth of the bottle to keep the straws in place. Put rubber glove at the cut end of the bottle.
