Bubble trouble

I mentioned the other day that I was experimenting with plaster, and made a bucket that had a hose coiled around the bottom which in turn was connected to a air compressor. Ok the idea was it would fill the setting plaster with air bubbles. What happened was, it did fill the plaster with air bubble, but rather small bubbles not aero type irregular type bubbles..

On research i can not find any data that discusses putting bubbles or air into plaster in fact everything i have read is regarding removing bubbles.

So I figured Well if you can get air bubble in to chocolate, why not plaster,. So I took a look at how the production of aero chocolate is manufactured

" They are made in a number of discrete stages beginning with deposition of unaerated shell chocolate into the bar moulds. A frozen cone shaped to fit into the bar is then pushed down to spread the liquid chocolate into the entire mould and set it. The aerated chocolate is then deposited into the centre and the moulds are shaken to distribute the chocolate evenly in the cavity. This is then chilled to set the bubbly chocolate in place before a final backing off deposit is created to give the back. The moulds are then shaken again to get a flat even back. The moulds are specially shaped to ensure that no meniscus is formed on the bottom, which can give the chocolate a scuffed appearance and also cause issues with the machines when they break off and build up. The bars are then chilled again for a longer period. This helps to make the chocolate contract for easier demoulding. The moulds are then tipped over and hammered to demould the bars, which then go to the packaging section."

On reflection i may have to rethink this small part of my FMP and look at an alternative to vulnerable plaster 

Ok speaking of bubbles it may be worth mentioning Ai Weiwei’s “Bubble,” a sprawling installation on the lawns of Watson Island, Miami, USA. It was  comprised of a 100 blue porcelain orbs (each is about 20 inches tall and about 30 inches in diameter, as you can see it made for any interesting installation. I would not say this piece inspires me, more interests me in the fact of the multi aspect and the shear sizes of the installiation.
