How to Make a Mini Flyable Hot Air Balloon with Candles

Steps:

Find a suitable plastic bag. Dry cleaning bags work well, but smaller garbage bags may also be used if they are very light weight. Such trash bags usually boast of high molecular density which usually translates to super thin, cheap, and flimsy. That happens to be what we're looking for. If you don't have any of these you can also use grocery bags.

Attach straws together to form a circle with a diameter of about 10 inches. Do this without glue or tape by twisting one end and inserting the end of that one into the another and so on.

Tape the opening of the opened bag to the circle of straws. Use light weight tape, and use it sparingly.

Cut a 2 inch square out of thin cardboard like from that of an empty cereal box. Cut four holes near the center (the holes should be slightly smaller than the width of the birthday candles so that they will fit snugly). Use trick candles for better results, because even if they blow out, they relight themselves.

Attach a twelve inch piece of thread to each corner of the cardboard square.

Insert candles into the holes you cut. You may need to adjust the center of gravity for our cardboard candle holder to hang properly. You may even put the wax on the Cardboard and Stick it on.
