Method:

Equipment

• Tea candle
• 4 straws
• 2 Bamboo sticks
• Medium-sized bin liner
• Bottle cap

Instructions

1. Get your equipment ready and be safe.
2. Glue your 4 straws together, make a cross then have two other straws on the outside.
3. Connect the bin liner to the straw so that it’s in a position that it will inflate when filled with air.
4. Put the bottle cap in the middle of the cross.
5. Light a fire with the tea candle and give it a little bit of support by holding it until you’re sure it can float on its own.
6. Once you’re happy with the result let the fire burn out then water down the cap.
