Further evidence that it's not what you say but how you say it, the Off Limits Voice Vault locks up your valuables and can only be opened with a voice-activated password. Although this is not exactly brand new, it does look like fun to record a codeword into this little safe ( open sesame, perhaps?), and once you close it, it opens for no one but you. It runs on a trio of AAA batteries, and is intended to be a toy, because there's no telling what happens when those batteries run out.
