many crude oil trains carry more than 100 cars and weigh 19,000 tons or more. each funnel was further linked to a plastic tube, which led into the enclosure. all contact details are available below or from the school office. i like to spend time with my husband in the evenings relaxing. i like the designs background in the last panel. so why not just use longer lengths of tubing? it’s what i love to see in action every day. it was okay nothing great so gave a few out to friends(need to stop this) had another a few weeks later and was much improved.
