If you can trust your nerve it is as well to keep the most difficult shot to the last, so as not to have an anticlimax. As a climax (if your conscience will permit you), give one or two “assisted” shots, so as to end brilliantly.
Always practise on the actual stage and with the same lighting as you will have to shoot under, when giving the exhibition.
If you do not do this you may find the light different, or so bad that you will not be able to do yourself justice.
A stage open to the sky, is, on a calm day, best of all, but there is the risk of a wind springing up. Always shoot on a stage elevated above the spectators so that all can see, and have the sun at your back.
On an open air stage you can finish as follows:
Have an old-fashioned .44 Winchester, black powder, repeating rifle. These can still be picked up at second-hand gunmakers’ shops.
Get cartridges for it loaded with No. 10 shot.
Have a lot of the rubber balls filled with water.
It looks most effective if the water is of various colours for alternate balls.
Get an assistant to throw them straight up as high as he possibly can, and break them in succession.
