(*_*) Earlier today at my high school I noticed an old support harness for carrying bells or drums while that looked perfect for using as a Slime Blower support system, I tried it out and It seemed pretty easy to modify!!! :-) Oh, by the way if you look up “marching drum harness” on Ebay you'll find a great selection of new and used harness, listings for support strap also popped up. check it out!!! (*peter)

It's a potential… but I wouldn't say it's a ‘perfect’ support harness, aside from anything else a person would have to wear it the wrong way around.

This is a diagram drawn by one of the Proptopia guys, showing the likely shape of the as-used harness in conjunction to the ALICE frame mounted to the ‘front’ of the Slime Blower.
