While testing our weather station, we realised that all our equipment was too heavy to take off. This proved to be a huge barrier to get over as we wanted to ensure that our equipment stays safe. Thus, we altered the design a bit and we managed to make it take off soon enough.

- We will need to ensure that our balloon does not fly up too high in the sky such that the balloon is lost and interferes with Singapore Air Safety regulations (http://www.caas.gov.sg/caas/en/Regulations/Airspace_Management/Air_Navigation_Hazard_x_Obstruction_Policies/Hot_Air_Balloon_Operations.html).
- The balloon may burst due to the tension the helium gives.
- We have never worked with helium before, so we have to be extremely cautious.
- Inhaling helium can cause oxygen deprivation and too much of this may lead to brain damage
- It is extremely important to be cautious of the weather (sudden downpour / lightning) as it will be disastrous if lightning strikes our weather balloon and we would get electrocuted in the process.
- Letting go of the balloon will lead to pollution
