I must have missed those episodes. We love Shark Tank, especially with Mark Cuban here in Dallas. We liked the light demonstration a week
or so ago with the UTD alum students (Ilumni) or something like that where your phone can control lighting!
As for bottles, I buy bottled spring water at the grocery and rarely use the bottle again unless it's for watering plants, etc. I don't reuse them for my water bottle.
We are in the plastics business and have all the info on BPA and it has no effect to me. The only way you'll be harmed by BPA is to inject yourself with it on a daily basis. Of course, we and our manufacturers changed some formulas which means BPA free and basically you get a more expensive water bottle.
Same concept as people who fear arsenic and there are normal levels routinely on our hands. I see it as the government trying to scare people. But, I can re-write a formulation which has no BPA, everyone is happier and profits are higher for those like me and manufacturers.
I am not a camper nor own or have been in a pick up truck do I have no idea about the mattress.
I agree with you... love the show!
