Do you use animation in your PowerPoint presentations? If you do then you should know about Trigger Effects. In fact, this is an area which gets explored very seldom. However, if you use Trigger Effects in your PowerPoint presentations they will definitely add some multimedia muscle which will make an impressive look to your PowerPoint slides. Using these Trigger Effects any object can be turned into the action button on your PowerPoint slide. As an action button, your object is going to trigger the animation effect once it gets clicked. When a couple of objects are somehow related to each other, you can use this trigger effect in some way. For example you have a photo of watering can and a flower. These both photos can be placed on your PowerPoint slide. Once the watering can is clicked, your flower will start growing. This is a great way to illustrate the process of growth.
