1. Large balloon
- produce bigger buoyant, increase volume of air displace

2. Many hot air burner
- Heat up gas faster

3. Synthetic nylon balloon
- Air proof, light weight

4. Gas temperature is high
- Reduce density of air

5. Rattan basket
- Longer time impact, reduce impulsive force when landing

6. Fly on early morning @ late afternoon
- temperature is cooler so the balloon will rise higher
