- Nice Catapult Trebuchet Option Review by Ohio Mom
-
Value Quality Price I bought two of these kits: one we built as a catapult and the other as a trebuchet so that we could do a homeschool science experiment to test which machine threw further and if the weight/type of material affected the throwing distance. I and my 9-year-old son assembled the catapult. We had all of the pieces that we needed for assembly; however, the instructions were incorrect in saying that a screw and nut were included--instead, you're just supposed to use one of the two small screws included to attach the catapult basket. There's no nut and you don't need it. My husband and son assembled the trebuchet; he said that there was a slight problem with the cotter pin in hole #5 interfering with the cotter pin in hole #6. He worked around this by not inserting the end cotter pin in all of the way. We fired them both off today. These are small machines so they don't throw very far; the farthest distance we measured was 130 inches that the catapult could throw a paper ball. However, in general, the trebuchet threw things much farther than the catapult perhaps because it achieved a higher loft to its throws. I give this a thumbs up for a great way for kids to kinetically understand the difference between the two machines. Allow about 45 minutes for assembly per machine.

- Not complete Review by Jason

Quality Value Price This is an OK kit, however the wheels required glue to keep them on, had to replace one of the cotter pins with a screw because it wouldn't stay in place and the most annonying thing is that it does not come with a hooked mass as is implied by the picture on the website.
