The new AeroRacers “Mega Stretch” rubber band racer is the perfect problem solving hands-on, brains-on or STEM product. This educational racer will run on virtually any surface. The power unit consists of a rubber band coupled with string. Students learn about the advantages of using a pulley to redirect a force. In addition students will become familiar with terms like potential and kinetic energy, rotating mass, inertia and momentum, just to name a few.
Friction on the driving wheels can be varied for better acceleration and/or longer distance runs by using weights. Power can be adjusted as well.
The Mega Stretch racer can be modified to use one or two pulleys for improved performance. The pulley extension arm in the front of the vehicle can easily be added or removed to experiment with longer rubber band/string power units.
Students have to solve problems as they try to make their racer go faster and longer distances. The more power they use, the more problems they have to solve.
The racer can easily be decorated with markers. Students can design a body for their racer out of card stock paper (not included and not shown).
Students optimize their Mega STRETCH racers for long distance competitions, side by side drag racing and the ever popular mass launches.
All parts are pre-cut.
Overall Length: 11.5″
The chassis is designed to assemble in a very short time without glue.
We recommend you have a pair of scissors handy to cut the string to the desired length.
Our Mega STRETCH racer comes with all the parts needed for assembly:
laser cut plywood chassis and tool parts, wood wheels with O-rings and rubber bands, wooden axles, pulley, plastic axle tubing, high strength rear nylon axle, hex nuts as well as rubber string and kite string. Instructions are included.
