Using the wafers from two of the snack packs, place in a plastic bag and crush into small pieces for dusting.  Set aside.

Cut the bananas into slices and then quarter them.  Mix with a 1/2 tablespoon of lemon juice to prevent them from browning (you could skip this step if you are assembling and eating immediately).

Combine instant vanilla pudding mix with the milk and condensed milk and beat for 2 min.  Let sit for 5 min and then stir in cool whip.

Cut off one end of the nilla wafer packet and dump out the wafers.  Put half of them back in the bag, add 2-3 tablespoons of vanilla pudding mix and 2 tablespoons of quartered banana slices on top of that.  Now repeat the layering with the remaining wafers, more pudding mix, and bananas.  Complete all 10 packets.

Top each with a layer of Reddi-whip, wafer dusting, and lastly a maraschino cherry.

Serve immediately or let sit in fridge overnight.
