My list, in no particular order:
Crash Cars: Little plastic cars you put together with a spring inside. Roll 'em against the wall and they explode. Put 'em back together and repeat.
Tricky Walkers: Pull the string and they walk up the wall with suction cups.
Rockem Sockem Robots: Nuff said.
Kenner Bridge and Panel Building Set: Build roads, bridges, buildings, etc.
Slinky: Nuff said.
Mattel Varoom Engine: Put it on your bike and pretend it's a motor cycle.
"The Rifleman" Rifle: With that big ol' round cocking thing. Just like Lucas McCane's.
Give a Show Projector: Show chincy movies in your basement.
Auroral HO Racing: Nuff said.
After I sign out I'll think of 10 more.
I remember playing with everything on your list.
Were you my next door neighbor? He had all the cool stuff.
