If you are looking for a fun gift you need to take a look at the Double Doom Roller Coaster Building Set by K’NEX. My three boys have always enjoyed all of the K’NEX toys we have bought through-out the years. This one is recommended for age 9+ so it will be the prefect Christmas gift for our 10 year old this year.
It has over 16 feet of track and can be built to go over 3 feet high. In the kit is two coaster cars to equal double the trouble. The Double Doom Roller Coaster Building Set has 891 K’NEX pieces including classic rods and classic connectors. With the motorized action, your 2 coaster cars will go on a twisting and turning ride.
You can also download instructions for a 2nd coaster to have twice the fun building a second roller coaster!
Buy it on Amazon or any major toy retail store.
