I've been sending Hello Internet Hotstoppers to randomly selected HI Patrons. That will continue.

But I'll also send a few to randomly selected people who receive my emails.

To be in the running, you need to send an email to message4brady@gmail.com that meets the following criteria.

1. It must be sent from the same email address that's registered with my email list.

2. The subject line of the email must be the name of the 19th century scientist who may have sat in the THIRD chair featured in this week's Objectivity video.

3. The body of the email should include your name and postal address.

A random selection of correct entries will be chosen and a hotstopper sent your way. Winners won't be notified but your hotstopper will arrive before Xmas.
