ROBOT THAT MOVES WITHOUT WHEELS
CONTEST WINNER: RAJVEER & RIDHAM, INDIA!
From Rainbow International School in the foothills of the Himalayas, here come Rajveer and Ridham! Great work boys – not only does your invention move without wheels, it cleans the floor (or the table) while it’s at it!
CREATURE WITH SPINNING ARMS
CONTEST WINNER: SIMONE OF SAN CARLOS, CA!
Simone, we love your double-motor design, the way you used the shape of the wooden chassis to make a head, the feet made from wheels, and your creative use of yarn and paper to create a super cool and ultra-adorable creature. Great job getting those arms spinning super fast!
THE GREAT EGG SCRAMBLER
CONTEST WINNER: KATE OF WYLIE, TX!
Kate, we’re impressed by how you designed your invention to stand on its own over the bowl, the clever motor placement on the chassis, and the symmetry of the whole machine. And, what a great idea to incorporate part of your dad’s weed eater. Fantastic Tinkering.
Zohar, very creative use of the axles and motors to create a powerful paddle wheel! We want to see it in the water!
Tinkerer Beckett, we love how you used the can and silver tape to make a robot body. Excellent use of outside materials!
ASHALIA + DYLAN
Nice handle! Great use of the L-brackets to both support the handle and hold the springs for the electrical connections. We also loved the double-wheel whisk stabilizer.
We love this minimalist design, Weston! The stacked wheels are a great way to increase rotational momentum and really show those eggs who’s boss. Simple and effective—great work.
Great design Zekariah, excellent use of the cards to make propellers. It looks like it would really gain speed if it had more room!
What an elegant stabilization solution, using the wheel and straight piece to hold the scrambler rods!
Excellent invention, Luke! The tape seems to hold the whisk very securely. We also like the way you used a wooden piece and bolts for a safe and sturdy electrical connection platform. Great work!
Great use of two offset wheels, Beckett, with a centered wheel in between – it’s a very clever way to create a wide diameter rotation!
Marcelo, this is an invention of elegant simplicity! Nice double-paddle spinning motion. With some adjustments to your wiring, we think you could also make it go straight if you want to.
Weston, this is an ingenious double-cup design. We like your use of the axle and wheels as arms. And the background music is the icing on the cake. Excellent job!
Bennett, we love how you boldly plunge the wooden pieces into the egg! Great double-gearwheel scrambler. Thanks for sending both the video and picture so we can really see your invention.
Ingenious pistol-grip configuration! We also really like your motor holder made from two wood pieces, and the strategic battery placement.
Mr. Crazy is crazy awesome! Placing the motor off-center on the wheel is brilliant. We love your use of the plastic jar and how you created and decorated his face and head.
Evan, thank you for showing us true Tinkering in action! It is great to see all the different difficulties you had to overcome on the way to an awesome egg scrambler. Your final invention is fantastic—we love the way you decided that one scrambler rod is actually better than two. And the video is amazing – we can’t wait for Episode 2!
Chopsticks! Genius! And, your invention also meets Challenge #1: Create something that can make a loud noise. Two for one!
Alexie, we love this design! Brilliant use of the box as a stand—it looks like it works perfectly. We like how you used twist-ties to secure your wires in a place where rubber bands might have been hard to apply. Fantastic!
