 Finally, test your full scale. You don't want to take all 30 samples or build 30 different buildings. You can do small samples, meaning 12 foot by 12 foot here at the BLS and down select those that perform the best and start testing those and then take your final design out and do the high explosive field event where everybody sees the fireball and you see the results from it. And we're very excited about that. We like to see the fireball too. Absolutely. I want to see the fireball. Yeah.
