DIY the NASA-inspired airless bike tires using PVC pipes, bolts and nuts. Watch the video!

Popular DIY and science YouTube channel, The Q took his viewers through the process of replacing his bicycle’s traditional rubber tires with a set of airless ones put together with an old PVC pipe and some nuts and bolts.

We’ve seen airless tires on construction vehicles, like backhoes and skid steers, and smaller vehicles like golf carts and lawnmowers. No one wants a flat tire while mowing the lawn or playing golf and the chance for a flat tire is far higher in places like construction zones and building demolition sites. It makes sense that some vehicles prioritize airless tires and some don’t, but what about bicycles?

The Q, popular science and DIY YouTube channel, asked the same question and looked no further than an old PVC pipe and some nuts and bolts to answer it. Before constructing his airless tires, The Q was sure to pick a PVC pipe that had enough density to support a rider and ride well on different terrain. Settling on a ½” thick PVC pipe, The Q then sliced the PVC pipe into two-inch wide rings. From there, the DIY YouTuber connected all of the rings into a single link after drilling three holes into each and joining them together with nuts and bolts.

The Q then drilled corresponding holes into the rim of the bike, linking those holes with the ones previously drilled into the PVC rings. Reinforcing that layering with nuts and bolts, The Q repeated the process for two more rows, resulting in a triple overlay of PVC rings. With the main job complete, The Q finalized the project by carving the top layer of rubber from the bike’s original tire before laying it over the rows of PVC rings and gorilla gluing all of the pieces together. From there, the airless tires were ready to hit the road.

While The Q admits that the overall construction could benefit from slight modifications, the bike’s airless tires are fully functional and can ride smoothly over varying terrains, from sand to grass, and from pavement to gravel.

Circular saw blades replace the tires of this classic road bike to help it ride on ice!

Across the globe, it seems a cold front has a lot of us in its grips and cooped up indoors. No longer are we riding bikes in the sun or enjoying the outdoors, instead, we’re suffering through the double whammy of a cold winter and this endless quarantine. But for some of us, the frozen lake left in the wake of a winter storm’s rage only coaxes us from hibernation, offering more territory for us to play. For The Q, a video-content creation channel known for its quirky science videos that solve engineering problems, a frozen lake provided the ideal conditions to test out their latest project, Icyclycle  – a road bike whose tires were replaced with giant, circular saw blades.

In order to get their bike, a Corso Number One Spirit, primed for the ice, The Q entirely disassembled the bike’s 26-inch wheel systems. The tires were deflated, the spokes were removed, and the cog was soldered. The road bike’s rear cassette was first broken down into its individual components in order to then be welded and fitted for the incoming circular saw blades. Placing the round saw blades between the bike’s rear chainstays, the bike’s original chains accommodated the new saw-tires with help from a welded disc wheel. As shown in the video, once the new circular saw blades were put in place and ready to hit the ice, The Q’s initial test run didn’t go as planned.

The bike moved too deep along the y-axis, digging deeper into the ice instead of moving forward. Noticing this mechanical issue, The Q returned to the metal shop for some acute fixes that required welding small horizontal metal fixtures to the ends of each tooth around the circular saw-blade-tires. The smart fix eventually led to the success of Icyclycle since it allowed the saw-blade to simultaneously pick up and collect the ice it moved on, allowing for less force to be applied to the ground as the bike moved forward.

Quarantine is turning a lot of us into self-proclaimed DIY-buffs and this winter isn’t helping, but The Q is in a league of its own. I’d go so far as to say that when it comes to surviving this winter, The Q came, saw, and conquered.

Replacing the road bike’s tires with circular saw blades, The Q set out to create a hybrid bike that runs on ice.

Deconstructing the road bike’s original wheel system meant completely disassembling the rear wheel cassette.

The spokes were removed from both of the wheel’s hubs so that they could be adjusted to accommodate the bike’s new ice-wheels.

The disc wheel worked to help fasten and protect the steel saw blades while also providing positive friction for the bike wheels to properly rotate.

Once the road bike’s hubs were fit for the saw-blades, the new ice-wheels were easily inserted between the bike’s chainstays.

Without any means to move past the ice, the circular saw-blades’ teeth only dug further into the ice as the bike’s wheels rotated.

The design behind this wheel turns it into a type of track wheel that is commonly seen on construction sites or during the early morning hours following a bad snowstorm, as track wheels make it harder for vehicles to sink into the ground.

Building a Super Mario Bros. Maze for a Rat

Do you have a pet rat? Do you want to build a maze for him or her to hang out in? If so, you might as well make a geeky one – something that will entertain you as much as it does your rat friend. A maze that looks like a level from Super Mario Bros. should do the trick.

Maker The Q built this colorful rat maze using just cardboard, hot glue, paint, and a sheet of clear acrylic for the front. It’s pretty awesome, but easy to make your own with a little skill and patience. His rat named Shelly figures out how to make it through to the end with no problems at all. There’s not even a single Goomba or Koopa. It can’t even collect any coins or use the warp pipes. Imagine how disappointing that is to a rat.

Designing a rat maze is like designing a video game – you don’t want to make it too easy for them. Include some Hammer Bros. to toss hammers at it. Some lava lakes. Spike pits are a nice touch too. Chain Chomps? You know it. You can’t go too easy on rodents. They want a challenge.

F1 Race Car Replica Built from Coke Cans Is Sure to Fail Any Crash Test

If you’ve ever wanted to build your own Formula 1 race car out of coke cans, this cool video will show you how. The Q channel recently built a giant Coca-Cola F1 race car using Coke and Coca-Cola Light cans, PVC pipe, and glue. All pretty simple materials to work with.

I would have built the entire thing out of Coke cans though because everyone knows that the diet stuff isn’t as fast. Strike that. I would have used Monster Energy drinks because those will get your heart racing, so they are obviously the speediest. Anyway, it took The Q almost 1000 empty coke cans, 5 different types of glue, over 12 meters of PVC pipe, and over 400 man hours to build this thing.

The scale of the car is roughly 1:1.5 scale compared to the original F1 car. The final result is a very cool and detailed work of art that will NOT stand up to a crash at all. It won’t even stand up to someone getting in it, or even being breathed on the wrong way. It’s still pretty awesome though. Is it bad that I want to see it crushed in a real race? I know, this is why I can’t have nice things.
