"Hrmm?" Edward says as she draws his attention back to his food. That makes him blink in surprise but he saw some sense in her suggestion, we was rather peckish though he could have sworn he'd eaten recently. So he tucks into the meal as they standing contemplative silence for a moment until she makes a suggestion.

"Hrmmm, Bicarbonite and water. An interesting proposition. Would be a relatively simple thing to set up, would just need a system to dump the bicarbonate into water during heat. Would need to check the rate of expansion on the reaction as well as if it would be more effective than just regular water. Obviously, that caries the risk of water damage but that at least doesn't threaten the structural integrity of the house." He is ounce again tapping his fork against his plate but at least most of the meal was consumed now.
