This idea works great for a kids party OR an office full of engineers. I did it for the latter as a surprise for my husband's birthday. He loves Lego's, and I remember having Lego-style candy as a kid but I haven't been able to find it since then. I finally found it online here for a good price (amazon has it for more) and made it into small favors for Q's office. It tastes like SweetTarts and the best part is that you can actually build things with it - which, for the record, they did.
By the way, Q's brother Thad works with him and always delivers stuff like this for me. Thanks, Thad.
