Hot air balloon 

With lil Morphett and Felix. Using plastic bag and stick to make a parachute, then wrapping tin foil around the parachute stick to prevent it from setting on fire.

birthday candles to create hot air to make it go up, which failed because not enough heat.

Tried again  with cotton balls soaked with methylated spirits on the end of burning stick, but failed because the bag was too small and it melted. trying again next time with big black rubbish bag so it has more space so it doesn't melt, and using multiple cotton balls soaked with methylated spiritsfor more speed.
