These are the inflatable remote-controlled shark and clownfish that swim through the air with the same graceful movements as underwater. Unlike other neutrally buoyant aircraft with dedicated vector propellers, they use reciprocating tail fins that provide forward motion, just as a real shark’s or clownfish’s tail pushes against water. Deft control of the infrared remote transmitter’s rocker-arm switch moves the tail back and forth for propulsion indoors up to 10' away within line of sight. Faster switching results in vigorous “swimming” while holding the switch in the left or right position executes wide, arcing turns. A weighted ventral pod slides forward and backward on a fixed rail at the remote’s command, raising or lowering its pitch for climbs or descents. Mylar construction; helium available at any party supply store. Requires four AAA batteries. Select Shark or Clownfish. Ages 8 and up. 57" L x 24" W x 36" H. (6 oz.)
