Today my son purchased a Ja-ru cap gun and caps. UPon firing the first cap, the gun burst into flames and melted. It caused a minor burn on his hand. I understand that there is a hazard when using any caps. My problem is that with todays toy standards, how is it possible that toy makers can place so much of the flammable substance into these caps to cause a hard plastic toy to melt almost immediately. This is a real safety hazard for children that play with this toy.
