You can construct a Wall Coaster race track with the same basic parts.

Here’s how...

Place two balls of putty on one 4 or 10 inch track

Stick 2 pieces of track together as shown above

Stick a 4 or 10 inch piece of track to the wall and then a small ball of coaster tack on the inside of the track as shown above.

Place the two pieces of track that you created in step 2 on top of the track that you just secured to the wall and push towards the two balls of coaster tack in order to secure the racing track. This can be a little tricky but you will get the hang of it pretty quick. Continue this process and connect the double track runs similar to the single runs. Soon you will have a side-by-side race track!
