The Balloon Port will sit between the Funhouse and the Ferris Wheel with each providing access. There is a platform from the Fun House roof and we will have a special rule for the Ferris Wheel, maybe expending 1 MA and 1 SA to interact with the Ferris Wheel (or something like that). It is also less than 30cm high for Batclaw access.
I needed a basket for the balloon and this was assembled using foam board, cocktail stick dowels, PVA and 4 BBQ skewers. I added a layer sellotape later to give strength.
Then I needed something to link the balloon to the basket.
The loading would be vertical and downwards through the wooden skewers. I cut out a larger piece of foam board and took a nick out of each corner. These would house the top end of the skewers which would also be pushed outwards into a small curve which should look good. I then glued four squares over the top of these holes. I tried adding tape but without great success.
Now I needed to connect the ballon. It also had to be removable for easy storage later. I went with the idea of an upturned Coke plastic bottle which has a curved bottom and would sit well inside the top of the balloon. I cut off the mouth piece and then cut out two large vertical slots in the shape of the foam board top platform.
This worked a treat and the Coke bottle sat on top of the foam board in a stable way.
I was delighted. All that needed to happen now was to add the balloon itself.
And there we have it - one balloon. It dominates the playing table and I am thinking of painting it up like a Joker's head.
Then it will be ready for the Joker to invade Arkham, dropping poison gas or whatever his wicked plan might be. Can Batman & Robin stop him, that is the question?
Thanks for all the ideas guys.
