I use regular party balloons. I use a pump to blow them up. The messes I have funneled into an empty 2 litter soda bottle. I stretch the balloon out over top of the bottle and then turn it upside down. The air is forced out of the balloon and into the bottle forcing the contents into the balloon. Some times with thicker items you have to squeeze the bottle some to help them out. Then pinch the balloon closed with your fingers before removing it and tieing it off. Tieing it off if the hardest part and I have not found any short cuts to that. I keep meaning to make a video when I do one since people keep asking. Also spray stuff like whip and shaving cream are easy blow it up part way and incert the nozzle and spray just remember the gas that causes them to spray will also blow the balloon up more so leave room for it.
Love you, too
