This is not a ride in a hot air balloon. It is a helium balloon tied to a string with a pulley that takes you up and down. While I am loathed to bring attention to this attraction, as I bought an inflated and misleading Groupon for it, I feel I would be omitting an interesting activity if I ignored it completely.
Here is the deal: a 15 minute balloon ride in a Hyundai sponsored helium balloon that hovers 120 above the ground. It happens in Montecasion, Sandton and Soweto. I went to the Montecasino one and had a nice view of the bird park, William Nichol, and the Magaliesberg mountain range. It costs R75 for a normal ride, and R150 for a sunrise or sunset ride (which provides champagne and chocolates). I went on the sunset one, and the whole thing is pretty decent fun. If you are a pensioner you pay R45. There were alot of pensioners when I was there, and it is pretty tame.
