Haha, cute. I was told the same thing by the lady that sold me mine: "oh, just use 4 metal clips for each corner of your tank, that ought to be enough to keep her from escaping". Well, I have horrible insomnia, and luckily woke up at 3am one night to find my ball halfway out of one corner of my tank, with all four metal clips in place. After a series of "hell naw"s, I bought an extra four metal clips to keep her in place. I now have a lot of respect for the fact that balls are constrictors for a reason: they're just long, slithering bodies of muscle. I'm afraid that once she gets larger, I'll have to secure the tank with bricks
