The Disk Utility method is the way to go for people who are more comfortable in the Finder (though it does require a couple Terminal commands), and it works under Snow Leopard, Lion, Mountain Lion, Mavericks, and Yosemite. (Note that the createinstallmedia tool doesn’t work under OS X 10.6 Snow Leopard-it requires OS X 10.7 Lion or later.) The createinstallmedia method is the easiest if you’re at all comfortable using Terminal, it’s the approach that I recommend you try first.

I’ve come up with three ways you can create a bootable OS X install drive for the Yosemite: using the installer’s built-in createinstallmedia tool using Disk Utility or performing the Disk Utility procedure using Terminal.

In the future, if you wish to boot from your previous OS version, just restart, holding down the Option key.

Launch the installer and it will display a splash screen.

My flash drive came with some oddball DOS-based format I erased it in Disk Utility, then created one full-sized partition set up as Mac OS Extended (Journaled). You just need to make sure that it's properly formatted and partitioned. I picked up a PNY 64 GB USB 3.0 drive from Amazon for US$26 perfect for installing Yosemite, Xcode 6, or other apps that you'd like to test with OS X 10.10.
